Module 9: 2D Dynamic Programming

Longest Common Subsequence

Dissected from recursive tree intuition to space-optimized DP table. Mastered across strings, arrays, and subsequence patterns.

Time Complexity:O(M × N)
Space Complexity:O(N) [Optimized]

Live Mentor Tip: “Notice how dp[i][j] only depends on the previous row. We can compress space from O(MN) to O(N)!”

def longestCommonSubsequence(text1: str, text2: str) -> int:
    m, n = len(text1), len(text2)
    dp = [0] * (n + 1)

    for i in range(1, m + 1):
        prev = 0
        for j in range(1, n + 1):
            temp = dp[j]
            if text1[i-1] == text2[j-1]:
                dp[j] = prev + 1
            else:
                dp[j] = max(dp[j], dp[j-1])
            prev = temp
    return dp[n]
