- ==> arithmetic/tests.for.divisibility/seven.p <==
- What is the test to see if a number is divisible by 7?
-
- ==> arithmetic/tests.for.divisibility/seven.s <==
- Take the last digit (n mod 10) and double it.
- Take the rest of the digits (n div 10) and subtract the doubled last
- digit from it.
- The resulting number is divisible by 7 iff the original number
- is divisible by 7.
-
- Example: Take 2009.
- Subtract (2009 mod 10) * 2 from (2009 div 10)
- - 9 * 2 + 200
- = 182
- Subtract (182 mod 10) * 2 from (182 div 10)
- - 2 * 2 + 18
- = 14
- so 2009 is divisible by 7.
-
- ==> arithmetic/tests.for.divisibility/three.p <==
- Prove that if a number is divisible by 3, the sum of its digits is likewise.
-
- ==> arithmetic/tests.for.divisibility/three.s <==
- First, prove 10^N = 1 mod 3 for all integers N >= 0.
- 1 = 1 mod 3. 10 = 1 mod 3. 10^N = 10^(N-1) * 10 = 10^(N-1) mod 3.
- QED by induction.
- Now let D[0] be the units digit of N, D[1] the tens digit, etc.
- Now N = Summation From k=0 to k=inf of D[k]*10^k.
- Therefore N mod 3 = Summation from k=0 to k=inf of D[k] mod 3. QED

- ==> combinatorics/coinage/combinations.p <==
- How many ways are there to make change for a dollar? Count
- combinations of coins, not permuations.
-
- ==> combinatorics/coinage/combinations.s <==
- Assuming that you had coins of one cent, five cents, ten cents, 25 cents,
- 50 cents, and 100 cents, there are 293 ways to make change for a dollar.
- This can be calculated by determining the number of ways to make change
- using only a penny and then a penny and nickel, then penny, nickel, and
- dime, etc.
-
- The table is shown below:
-
- Amount 00 05 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100

-
- The meaning of each entry is as follows:
- If you wish to make change for 50 cents using only pennies, nickels and dimes,
- go to the .10 row and the 50 column to obtain 36 ways to do this.
-
- To calculate each entry, you start with the pennies. There is exactly one
- way to make change for every amount. Then calculate the .05 row by adding
- the number of ways to make change for the amount using pennies plus the number
- of ways to make change for five cents less using nickels and pennies. This
- continues on for all denominations of coins.
-
- An example, to get change for 75 cents using all coins up to a .50, add the
- number of ways to make change using only .25 and down (121) and the number of
- ways to make change for 25 cents using coins up to .50 (13). This yields the
- answer of 134.

- ==> combinatorics/coinage/dimes.p <==
- "Dad wants one-cent, two-cent, three-cent, five-cent, and ten-cent
- stamps. He said to get four each of two sorts and three each of the
- others, but I've forgotten which. He gave me exactly enough to buy
- them; just these dimes." How many stamps of each type does Dad want?
- [J.A.H. Hunter]
-
- ==> combinatorics/coinage/dimes.s <==
- The easy way to solve this is to sell her three each, for
- 3x(1+2+3+5+10) = 63 cents. Two more stamps must be bought, and they
- must make seven cents (since 17 is too much), so the fourth stamps are
- a two and a five.
-
- ==> combinatorics/coinage/impossible.p <==
- What is the smallest number of coins that you can't make a dollar with?
- I.e., for what N does there not exist a set of N coins adding up to a dollar?
- It is possible to make a dollar with 1 current U.S. coin (a Susan B. Anthony),
- 2 coins (2 fifty cent pieces), 3 coins (2 quarters and a fifty cent piece),
- etc. It is not possible to make exactly a dollar with 101 coins.
-
- ==> combinatorics/coinage/impossible.s <==
- The answer is 77:
-
- a) 5c = 1 or 5;
- b) 10c = 1 or 2 a's (1,2,6,10)
- c) 25c = 1 or 2 b's + 1 a
- d) 50c = 1 or 2 c's
- e) $1 = 1 or 2 d's

- ==> combinatorics/color.p <==
- An urn contains n balls of different colors. Randomly select a pair, repaint
- the first to match the second, and replace the pair in the urn. What is the
- expected time until the balls are all the same color?
-
- ==> combinatorics/color.s <==
- (n-1)^2.
-
- If the color classes have sizes k1, k2, ..., km, then the expected number of
- steps from here is (dropping the subscript on k):
-
- 2 k(k-1) (j-1) (k-j)
- (n-1) - SUM ( ------ + SUM --------------- )
- classes, 2 1<j<k (n-j)
- class.size=k
-
- The verification goes roughly as follows. Defining phi(k) as (k(k-1)/2 +
- sum[j]...), we first show that phi(k+1) + phi(k-1) - 2*phi(k) = (n-1)/(n-k)
- except when k=n; the k(k-1)/2 contributes 1, the term j=k contributes
- (j-1)/(n-j)=(k-1)/(n-k), and the other summands j<k contribute nothing.
- Then we say that the expected change in phi(k) on a given color class is
- k*(n-k)/(n*(n-1)) times (phi(k+1) + phi(k-1) - 2*phi(k)), since with
- probability k*(n-k)/(n*(n-1)) the class goes to size k+1 and with the same
- probability it goes to size k-1. This expected change comes out to k/n.
- Summing over the color classes (and remembering the minus sign), the
- expected change in the "cost from here" on one step is -1, except when we're
- already monochromatic, where the handy exception k=n kicks in.
-
- One can rewrite the contribution from k as
-
- (n-1) SUM (k-j)/(n-j)
- 0<j<k
-
- which incorporates both the k(k-1)/2 and the previous sum over j.
- That makes the proof a little cleaner.
-
- ==> combinatorics/full.p <==
- Consider a string that contains all substrings of length n. For example,
- for binary strings with n=2, a shortest string is 00110 -- it contains 00,
- 01, 10 and 11 as substrings. Find the shortest such strings for all n.
-
- ==> combinatorics/full.s <==
- Knuth, Volume 2 Seminumerical Algorithms, section 3.2.2 discusses this problem.
- He cites the following results:
- Shortest length: m^n + n - 1, where m = number of symbols in the language.
- Algorithms:
- [Exercise 7, W. Mantel, 1897]
- The binary sequence is the LSB of X computed by the MIX program:
- LDA X
- JANZ *+2
- LDA A
- ADD X
- JNOV *+3
- JAZ *+2
- XOR A
- STA X
- [Exercise 10, M. H. Martin, 1934]
- Set x[1] = x[2] = ... = x[n] = 0. Set x[i+1] = largest value < n such that
- substring of n digits ending at x[i+1] does not occur earlier in string.
- Terminate when this is not possible.
-
- If we instead consider the strings as circular, we have a well known
- problem whose solution is given by any hamiltonian cycle in the de
- Bruijn (or Good) graph of dimension K. (Or equivalently an eulerian
- circuit in the de Bruijn graph of dimension K-1) As a string of length
- 2^K is produced, it must be optimal, and any shortest sequence must be
- an eulerian circuit in a dB graph.
-
- The de Bruijn graph Tn has as its vertex set the binary n-strings.
- Directed edges join n-strings that may be derived by deleting the left
- most digit and appending a 0 or 1 to the right end. de Bruijn + van
- Ardenne-Ehrenfest (in 1951) counted the number of eulerian circuits in
- Tn. There are 2^(2^(n-1)-n) of them.
-
- Some examples:
- K=2 1100
- K=3 11101000
- K=4 1111001011010000
-
- The solution to the above problem (non-circular strings) can be found
- by duplicating the first K-1 digits of the solution string at the end
- of the string. These are not the only solutions, but they
- are of minimum length: 2^K + K-1.
-
- We can obtain a lower bound for the optimal sequence for the general case as
- follows:
-
- Consider first the simpler case of breaking into an answer machine which
- accepts d+1 digits, values 0 to n-1. We wish to find the minimal universal
- code that will allow us access to any such answering machine.
-
- Let us construct a digraph G = (V,E), where the n^d vertices are labelled
- with a d sequence of digits. Notation: let [v_{i,1},v_{i,2},...,v_{i,d}]
- denote the labelling on node v_i. An edge e = (v_i, v_j) is in E iff for k
- in 1, ..., d-1: v_{i,k+1} = v_{j,k}, i.e., the last d-1 digits in the
- labelling of the initial vertex of e is identical with the first d-1 digits
- in the labelling of the terminal vertex of e. We associate with each edge a
- value, t(e) = v_{j,d}, the last digit in the labelling of the terminal
- vertex.
-
- The intuition goes as follows: we are going to perform a Euler circuit of
- the digraph, where the label on the current vertex gives the last d digits
- in the output sequence so far. If we make a transition on edge e, we output
- the tone/digit t(e) as the next output value, thus preserving the invariant
- on the labelling.
-
- How do we know that a Euler circuit exists? Simple: a connected digraph
- has an Euler circuit iff for all vertices v: indegree(v) = outdegree(v).
- This property is trivially true for this digraph.
-
- So, in order to generate a universal code for the AM, we simply output 0^d
- (to satisfy the precondition for being in vertex [0,...,0]), and perform an
- Euler circuit starting at node [0,...,0].
-
- Now, the total length of the universal sequence is just the number of edges
- traversed in the Euler circuit plus the initial precondition sequence, or
- n^d * n + d (number of vertices times the out-degree) or n^{d+1} + d. That
- this is a minimal sequence is obvious.
-
- Next, let us consider the machine AM' where the security code is of the form
- [0...n-1]^d [0...m-1], i.e., d digits ranging from 0 to n-1, followed by a
- terminal digit ranging from 0 to m-1, m < n.
-
- We build a digraph G = (V, E) similar to the construction above, except for
- the following: an edge e is in E iff t(e) in 0 to m-1. This digraph is
- clearly non-Eulerian. In particular, there are two classes of vertices:
-
- (1) v is of the form [0...n-1]^{d-1} [0...m-1] (``fat'' vertices)
-
- and
-
- (2) v is of the form [0...n-1]^{d-1} [m...n-1] (``thin'' vertices)
-
- Observations: there are (n^{d-1} * m) fat vertices, and (n^{d-1} * (n-m))
- thin vertices. All vertices have out-degree of m. Fat vertices have
- in-degrees of n, and thin vertices have in-degrees of 0. Color all the
- edges blue.
-
- The question now becomes: can we put a bound on how many new (red) edges
- must we add to G in order to make a blue edge covering path possible?
- (Instead of thinking of edges being traversed multiple times in the blue
- edge covering path, we allow multiple edges between vertices and allow each
- edge to be traversed once.) Note that, in this procedure, we add edges only
- if it is allowed (the vertex labelling constraint). We will first obtain a
- lower bound on the length of a blue covering circuit, and then transform it
- into a bound for arbitrary blue covering paths.
-
- Clearly, we must add at least (n-m)*(n^{d-1}*m) edges incident from the fat
- vertices. [ We need (n-m) new out-going edges for each of (n^{d-1}*m)
- vertices to bring the out-degree up to the in-degree. ]
-
- Let us partition our vertices into sets. Denote the range [0..m-1] by S,
- the range [m..n-1] by L, and the range [0..n-1] by X.
-
- Let S_0 = { v: v = [X^{d-1}S] }. S_0 is just the set of fat vertices.
- Define in(S_0) = number of edges from vertices not in S to vertices in S.
- Define out(S_0) in the corresponding fashion, and let excess(S_0) =
- in(S_0)-out(S_0). Clearly, excess(S_0) = n^{d-1}m(n-m) from the argument
- above. Generalizing the requirement for Eulerian digraphs, we see that we
- must add excess(S_0) edges from S_0 if the blue edges connected to/within
- S_0 are to be covered by some circuit (edges may not be travered multiple
- times -- we add parallel edges to handle that case). In particular, edges
- from S_0 will be incident on vertices of the form [X^{d-2}SX]. Furthermore,
- they can not be [X^{d-2}SS] since that is a subset of S_0 and adding those
- edges will not help excess(S_0). [Now, these edges may be needed if we are
- to have a circuit, but we do not consider them since they do not help
- excess(S_0).] So, we are forced to add excess(S_0) edges from S_0 to S_1 = {
- v: v = [X^{d-2}SL] }. Color these newly added edges red.
-
- Let us define in(S_1), out(S_1) and excess(S_1) as above for the modified
- digraph, i.e., including the red excess(S_0) edges that we just added.
- Clearly, in(S_1) = out(S_0) = n^{d-1}m(n-m), and out(S_1) = m*|S_1| =
- m*n^{d-2}m(n-m), so excess(S_1) = n^{d-2}m(n-m)^2. Consider S_0 union S_1.
- We must add excess(S_1) edges to S_0 union S_1 to make it possible for the
- digraph to be covered by a circuit, and these edges must go from {S_0 union
- S_1} to S_2 = { v: v = [X^{d-3}SL^2] } by a similar argument as before.
- Repeating this partitioning process, eventually we get to S_{d-1} = { v: v =
- [SL^{d-1}] }, where union of S_0 to S_{d-1} will need edges to S_d = { v: v
- = [L^d] }, where this process terminates. Note that at this time,
- excess(union of S_0 to S_{d-1}) = m(n-m)^d, but in(S_d) = 0 and out(S_d) =
- m(n-m)^d, and the process terminates.
-
- What have we shown? Adding up blue edges and the red edges gives us a lower
- bound on the total number of edges in a blue-edges covering circuit (not
- necessarily Eulerian) in the complete digraph. This comes out to be
- n^{d+1}-(n-m)^{d+1} edges.
-
- Next, we note that if we had an optimal path covering all the blue edges, we
- can transform it into a circuit by adding d edges. So, a minimal path can
- be no more than d edges shorter than the minimal circuit covering all blue
- edges. [Otherwise, we add d extra edges to make it into a shorter circuit.]
-
- So the shortest blue covering path through the digraph is at least
- n^{d+1}-{n-m}^{d+1}-d. With an initial pre-condition sequence of length d
- (to establish the transition invariant), the shortest universal answering
- machine sequence is of length at least n^{d+1}-(n-m)^{d+1}.
-
- While this has not been that constructive, it is easy to see that we can
- achieve this bound. If we looked at the vertices in each of the S_i's, we
- just add exactly the edges to S_{i+1} and no more. The resultant digraph
- would be Eulerian, and to find the minimal path we need only start at the
- vertex labelled [{n-1}^d], find the Euler circuit, and omit the last d edges
- from the tour.
-
- ==> combinatorics/gossip.p <==
- n people each know a different piece of gossip. They can telephone each other
- and exchange all the information they know (so that after the call they both
- know anything that either of them knew before the call). What is the smallest
- number of calls needed so that everyone knows everything?
-
- ==> combinatorics/gossip.s <==
- 1 for n=2
- 3 for n=3
- 2n-4 for n>=4
-
- This can be achieved as follows: choose four professors (A, B, C, and D) as
- the "core group". Each professor outside the core group phones a member of
- the core group (it doesn't matter which); this takes n-4 calls. Now the
- core group makes 4 calls: A-B, C-D, A-C, and B-D. At this point, each
- member of the core group knows everything. Now, each person outside the
- core group calls anybody who knows everything; this again requires n-4
- calls, for a total of 2n-4.

- ==> combinatorics/grid.dissection.s <==
- Given an n*m grid with n > m.
-
- Orient the grid so n is its width. Divide the grid into two portions,
- an m*m square on the left and an (n-m)*m rectangle on the right.
- Count the squares that have their upper right-hand corners in the

- ==> combinatorics/subsets.p <==
- Out of the set of integers 1,...,100 you are given ten different
- integers. From this set, A, of ten integers you can always find two
- disjoint subsets, S & T, such that the sum of elements in S equals the
- sum of elements in T. Note: S union T need not be all ten elements of
- A. Prove this.
-
- ==> combinatorics/subsets.s <==
- First, a couple of points:
-
- (1) All empty subsets of the 10 integers are disjoint and have the same sum.
- This doesn't make for a very interesting problem. Thus, we impose the
- additional restriction that S and T be non-empty.
- (2) The 10 integers must be pairwise distinct. Consider, e.g., the 10
- integers 1, 1, 1, 1, 1, 1, 1, 1, 1, and 1. There are no non-empty
- disjoint subsets with equal sums.
-
- Proof of puzzle:
-
- There are 2^10 = 1,024 subsets of the 10 integers, but there can be only 901
- possible sums, the number of integers between the minimum and maximum sums.
- With more subsets than possible sums, there must exist at least one sum that
- corresponds to at least two subsets. Call two subsets with equal sums A and B.
- Let C = A intersect B; define S = A - C, T = B - C. Then S is disjoint from T,
- and sum(S) = sum(A-C) = sum(A) - sub(C) = sum(B) - sum(C) = sum(B-C) = sum(T).

- ==> cryptology/Beale.p <==
- What are the Beale ciphers?
-
- ==> cryptology/Beale.s <==
- The Beale ciphers are one of the greatest unsolved puzzles of all time.
- About 100 years ago, a fellow by the name of Beale supposedly buried two
- wagons-full of silver-coin filled pots in Bedford County, near Roanoke.
- There are local rumors about the treasure being buried near Bedford Lake.
-
- He wrote three encoded letters telling what was buried, where it was buried,
- and who it belonged to. He entrusted these three letters to a friend and went
- west. He was never heard from again.
-
- Several years later, someone examined the letters and was able to break the
- code used in the second letter. The code used either the text from the
- Declaration of Independence. A number in the letter indicated which word
- in the document was to be used. The first letter of that word replaced the
- number. For example, if the first three words of the document were "We
- hold these truths", the number 3 in the letter would represent the letter t.
-
- One of the remaining letters supposedly contains directions on how to find
- the treasure. To date, no one has solved the code. It is believed that
- both of the remaining letters are encoded using either the same document
- in a different way, or another very public document.

- I have deposited in the county of Bedford about four miles from
- Bufords in an excavation or vault six feet below the surface
- of the ground the following articles belonging jointly to
- the parties whose names are given in number three herewith.
- The first deposit consisted of ten hundred and fourteen pounds
- of gold and thirty eight hundred and twelve pounds of silver
- deposited Nov eighteen nineteen. The second was made Dec
- eighteen twenty one and consisted of nineteen hundred and seven
- pounds of gold and twelve hundred and eighty eight of silver,
- also jewels obtained in St. Louis in exchange to save transportation
- and valued at thirteen [t]housand dollars. The above
- is securely packed i[n] [i]ron pots with iron cov[e]rs. Th[e] vault
- is roughly lined with stone and the vessels rest on solid stone
- and are covered [w]ith others. Paper number one describes th[e]
- exact locality of the va[u]lt so that no difficulty will be had
- in finding it.
-
- CLEAR for part 2, using only the first 480 words of the
- Declaration of Independence, then blanks filled in by
- inspection. ALL mistakes shown were caused by sloppy
- encryption.
