- If I had not spoken in haste earlier and actually THOUGHT about the problem,
- I would have found the answer to the above question in the first place.
-
- I'll give a hint with a full solution later:
-
- Consider the equivalence classes of the integers from 1 to 100 mod 3.
-
- There are 34 congruent to 1 mod 3 and 33 congruent (each) to 0 or -1.
-
- Another way is to look at the integers 1 to 100 written in balanced
- ternary and apply the pigeonhole principle.
