The problem is: Given two strings, write a method to decide if one is a permutation of the other. The problems have different levels of difficulty. brightness_4 Given a string, write a function to check if it is a permutation of a palindrome. Example #1: If you're working with combinatorics and probability, you may need to find the number of permutations possible for an ordered set of items. This will generate all of the permutations that end with the last element. rev 2021.1.8.38287, Stack Overflow works best with JavaScript enabled, Where developers & technologists share private knowledge with coworkers, Programming & related technical career opportunities, Recruit tech talent & build your employer brand, Reach developers & technologists worldwide, This doesn't seem to work anymore with the latest version of Scalaz.
