Longest Common Subsequence - Given two strings text1 and text2, return the length of their longest common subsequence. If there is no common subsequence, return 0. A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters.

A common subsequence of two strings is a subsequence that is common to both strings. Example 1: Input: text1 = "abcde", text2 = "ace" Output: 3 Explanation: The longest common subsequence is "ace" and its length is 3.
In-depth solution and explanation for LeetCode 1143. Longest Common Subsequence in Python, Java, C++ and more. Intuitions, example walk through, and complexity analysis. Better than official and forum solutions.
Jan 16, 2019 · We define $f[i][j]$ as the length of the longest common subsequence of the first $i$ characters of $text1$ and the first $j$ characters of $text2$. Therefore, the answer is $f[m][n]$, where $m$ and $n$ are the lengths of $text1$ and $text2$, respectively.
class Solution { public: int longestCommonSubsequence(string text1, string text2) { const int m = text1.length(); const int n = text2.length(); // dp[i][j] := the length of LCS(text1[0..i), text2[0..j)) vector<vector<int>> dp(m + 1, vector<int>(n + 1)); for (int i = 0; i < m; ++i) for (int j = 0; j < n; ++j) dp[i + 1][j + 1] = text1[i] == text2[...
Longest Common Subsequence LeetCode Solution – Given two strings text1 and text2, return the length of their longest common subsequence. If there is no common subsequence, return 0.
