Hi everyone,

I'm currently working on implementing the Longest Common Subsequence (LCS) algorithm in Python. I've been reading the blog page on the topic LCS algorithm in Python, but I'm still having some trouble understanding the dynamic programming approach.

Can anyone help me with the following:

1. How do I initialize the DP table?
2. What is the recursive relationship for the DP table?
3. How do I calculate the longest common subsequence?

I would really appreciate any help you can provide
