Modify your solution to Programming Problem 16 from Chapter 1 to validate the user's input. Your program will need to validate that both integers are pos- itive aad distinct from each other. In addition, ppe loop so that the user can continue to generate Pythagorean triples. Your program should terminate when the user enters - as the first integer. 21. The greatest common divisor (gea) of two positive integers X and V can be determined as follows Step then the gcd is Step divide X by finding the remainder rl neter and Step not 0 divide by ~1 and find the remainder r2. ...
