String Permutation Challenge
Here is another mathematical problem, where the trick is as much to discover the algorithm as it is to write the code: write a program to display all possible permutations of a given input string--if the string contains duplicate characters, you may have multiple repeated results. Input should be of the form
permute stringand output should be a word per line.
Here is a sample for the input cat
