WebCan you solve this real interview question? Permutation in String - Given two strings s1 and s2, return true if s2 contains a permutation of s1, or false otherwise. In other words, return true if one of s1's permutations is the substring of s2. Example 1: Input: s1 = "ab", s2 = "eidbaooo" Output: true Explanation: s2 contains one permutation of s1 ("ba"). Web2 mai 2012 · This is a simple Java function to print all possible permutations (including the smaller ones down to empty string ""). if you need to print only the same length permutations, just add if statement prior the print.
