Longest Palindromic Subsequence in JavaScript
A Longest Palindromic Subsequence in JavaScript refers to the longest sequence of characters within a string that reads the same backward and forward. It’s a non-contiguous subsequence, and the goal is to find the maximum length of such subsequences in a given input string.
Example:
Input: str = “w3wiki”
Output: EEKEE, 5
Explanation: The longest palindromic subsequence we can get is of length 5.
There are more than 1 palindromic subsequences of length 5, for example: EEKEE, EESEE, EEFEE, …etc.
