Longest Palindromic Subsequence:

Given a string, find the length of the longest subsequence that is a palindrome. A subsequence does not need to be contiguous but must maintain the order of characters.

• Define Variables: Define the variables needed to represent the dynamic programming table and any other relevant state information.

• Recurrence Relation: Derive a recurrence relation to compute the longest palindromic subsequence based on the characters of the string.

• Pseudocode: Write pseudocode to find the length and the actual longest palindromic subsequence.

• Complexity Analysis: Analyze the time and space complexity of your solution
