There are many ways to find the `longest palindromic substring`. One can find it in $O(N ^ 3)$ and also in $O(N ^ 2)$ time complexity. But using `Manacher's Algorithm ...
This method has a time complexity of O(n³): one layer for the start index, one for the end index, and another for checking if the substring itself is a palindrome (which takes O(n) time). Clearly, ...
Abstract: The Longest Palindromic Substring (LPS) problem is a classic and fundamental task in string processing with broad applications in bioinformatics, natural language processing, data security, ...
