- 1) to different permutations. A recursive approach (which is what I would use) would involve breaking the problem into isomorphic subproblems: to find all permutations of a string, find all ...

If a string contains duplicate characters and we try to generate the permutations of the string (i.e., permutations of all the characters in the string, where n=r in nPr), then duplicate permutations ...

In this programming assignment, you will design in pseudo code and implement in Java two versions of a program that deals with two strings, referred to as shortStr and longStr. The program attempts to ...
