LeetCode 516. Longest Palindromic Subsequence 原题链接在这里:https://leetcode.com/problems/longest-palindromic-subsequence/ 题目: Given a string s, find the longest palindromic subsequence's length in s. You may assume that the maximum length of s is 1000. Example 1: Input: "bbbab" Output:...
leetcode 300. Longest Increasing Subsequence Given an unsorted arrayofintegers,find the lengthoflongest increasing subsequence.For example,Given[10,953,7101,18],The longest increasing subsequence is[2,3,7,101],therefore the length is4.Note that there may be more than oneLIScombination,it is only...
Example: String A = " AABCDEBAZ"; Longest Palindromic subsequence: ABCBA or ABDBA or ABEBA There are many subsequences can be found which are palindrome like, AA, BCB, ABA, BB etc but we need to find the one with the maximum length. Approach: Recursion: Check every subsequence of in a...
这道题好理解,但是要自己想的话还是很难想出来的,动态规划说白了就是记录当前的结果,留给后面的用。 求最长合法匹配的长度,这道题可以用一维动态规划逆向求解。假设输入括号表达式为String s,维护一个长度为s.length的一维数组dp[],数组元素初始化为0。 dp[i]表示从s[i]到s[s.length - 1] 包含s[i] 的...
