WebFeb 22, 2024 · Let the given number be num.A simple method for this problem is to first reverse digits of num, then compare the reverse of num with num.If both are same, then return true, else false. Following is an interesting method inspired from method#2 of this post. The idea is to create a copy of num and recursively pass the copy by reference, … WebFollowing is the C++, Java, and Python implementation of the idea: C++ Java Python Download Run Code Output: The longest palindromic substring of ABDCBCDBDCBBC is BDCBCDB The time complexity of the above solution is O (n2) and requires O (n) extra space, where n is the length of the input string.
