Given two strings
s2, write a function to return true if
s2 contains the permutation of
s1. In other words, one of the first string’s permutations is the substring of the second string.
Input: s1 = "ab" s2 = "eidbaooo" Output: True Explanation: s2 contains one permutation of s1 ("ba").
Input:s1= "ab" s2 = "eidboaoo" Output: False
- The input strings only contain lower case letters.
- The length of both given strings is in range
