Input: "pwwkew" Output: 3 Explanation: The answer is "wke", with the length of 3. Note that the answer must be a substring, "pwke" is a subsequence and not a substring. 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/longest-substring-without-repeating-characters著作权归领扣...
Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. Example 1: Input: "babad" Output: "bab" Note: "aba" is also a valid answer. Example 2: Input: "cbbd" Output: "bb" 方法一,动态规划 dp[i][i]=1 dp[i][i...
Given a string, find the length of the longest substring without repeating characters. Examples: Given"abcabcbb", the answer is"abc", which the length is 3. Given"bbbbb", the answer is"b", with the length of 1. Given"pwwkew", the answer is"wke", with the length of 3. Note that...
