【Leetcode】300—Longest Increasing Subsequence

一、题目描述给定一个无序的整数数组，找到其中最长上升子序列的长度。示例：输入:[10,9,2,5,3,7,101,18]输出:4解释:最长的上升子序列是[2,3,7,101]，它的长度是4。二、代码实现方法：动态规划法LISList[i]表示到第i位时最长上升序列的长度。显然LISList[0]=1。对于任意的i不为零的情况，应该在i的左侧找一个下标j，其满足两个条件：nums[j]比nums[i

2019牛客第五场G题 (subsequence 1) DP

题意：给一个数字字符串s和t，求s中有多少个子序列比t更大题解：如果子序列比t更长，那么只要开头不是0都可以，暴力枚举做这件事就好了。问题在于子序列和t等长的情形。从前往后考虑很麻烦，试着从后往前考虑：dp[i][j]表示的是s中以i开始的后缀的子序列匹配了t的j以后的子串。于是有:$$dp[i][j]=\begin{cases}dp[i+1][j]+dp[i+1][j+1]&s[i]=t[j]\

【动态规划】最长公共子序列问题（Longest common subsequence problem）

子序列（subsequence）是包含在string里的序列，它不需要连续，可间断。因为一个string有2^N个子序列，所以如果用穷举法（bruteforcemethod），则需要O（2^N）次。
