Teaching Kids Programming: Videos on Data Structures and Algorithms Given a string s, find any substring of length 2 which is also present in the reverse of s. Return true if such a substring exists, and false otherwise. Example 1: Input: s = “leetcode” Output: true Explanation: Substring “ee” is of length 2 which is also present in reverse(s) == “edocteel”. Example 2: Input: s = “abcba” Output: true Explanation: All of the substrings of length 2 “ab”, “bc”, “cb”, “ba” are also present in reverse(s) == “abcba”. Example 3: Input: s = “abcd” Output: false Explanation: There is no Continue Reading »
