Multiplicative Inverses Mod n Write a program which takes in two integers a, and n. Your job is to ensure that they are both positive integers (just to reinforce positivity, zero is not legal input either). Then your objective is to find out if there is an integer x so that a times x is 1 mod n. Sometimes they exist, and sometimes they won't. Test all possibilities between 1 and n to see if they work.
