Asubsequenceof 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. For example,"ace"is a subsequence of"abcde". Acommon subsequenceof two strings is a subsequence that is common ...
leetcode 1143. Longest Common Subsequence 一、题意 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 。二、解法 解法: 动态规划 dp[i][j]代表从text1[1:i]和text2[1:j]最长公共子序列的长度(从起始下标1开始): text1[i]==text2[j...
