README ¶ 567. Permutation in String Description 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"). Example 2: Input: s1 = "ab", s2 = "eidboaoo" Output: false Constraints: 1 <= s1.length, s2.length <= 10^4 s1 and s2 consist of lowercase English letters.
