Section Recap

What we learned

Look at what you can do now:

1.1. Solve LCS with 2D DP using match/skip transitions

2.2. Reconstruct the actual LCS by backtracking

3.3. Solve Edit Distance with insert/delete/replace operations

4.4. Reduce problems to LCS (palindrome, delete operation)

5.5. Recognize string DP patterns: two sequences, character comparison, 2D table These patterns form the foundation of string algorithms. When you see two strings and need to compare or convert them, think LCS or Edit Distance first.
