Leetcode: Longest Common Subsequence Given two strings text1 and text2,returnthe length of their longest common subsequence. A subsequence of a string is anewstring generated from the original string with some characters(can be none) deleted without changing the relative order of the remaining cha...
@ 1.问题描述 给定两个字符串 text1 和 text2,返回这两个字符串的最长 公共子序列 的长度。如果不存在 公共子序列 ,返回 0 。 一个字符串的 子序列 是指这样一个新的字符串:它是由原字符串在不改变字符的相对顺序的情况下删除某些字符(也可以不删除任 何字符)后组成的
class Solution { public int longestCommonSubsequence(String text1, String text2) { int m = text1.length(); int n = text2.length(); int[][] dp = new int[m+1][n+1]; for(int i = 0; i <= m; i++) dp[i][0] = 0; for(int j = 0; j <= n; j++) dp[0][j] = ...

Acommon subsequenceof two strings is a subsequence that is common to both strings. Example 1: Input:text1 = "abcde", text2 = "ace"Output:3Explanation:The longest common subsequence is "ace" and its length is 3. Example 2: Input:text1 = "abc", text2 = "abc"Output:3Explanation:The...
