Other palindromes like "kssk" or "eeksskee" are shorter. In this tutorial, we will learn about Python lists (creating lists, changing list items, removing items, and other list operations) with the help of examples. We then find the smallest positive index from these values to find the first non-repeating character. Examples: Input: s = "forgeeksskeegfor" Output: "geeksskeeg" Explanation: The longest substring that reads the same forward and backward is "geeksskeeg". Given a string s, find the longest substring which is a palindrome. Python developers often struggle to check if items exist in lists, strings, or other data structures efficiently. Here is an overview: When working with strings in Python, you may need to extract every possible overlapping substring grouped by length.
