Next Greater Permutation Of Digits
February 28, 2012
We have another interview question today:
Given a number, find the next higher number that uses the same set of digits. For instance, given the number 38276, the next higher number that uses the digits 2 3 6 7 8 is 38627.
Your task is to write a function to find the next greater permutation of digits. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
