题目 最长无重复字符的子串给定一个字符串,请找出其中无重复字符的最长子字符串. 例如,在"abcabcbb"中,其无重复字符的最长子字符串是"abc",其长度为 3. 对于,"bbbbb",其无重复字符的最长子字符串为"b",长度为1. 解题 利用HashMap,map中不存在就一直加入,存在的时候,找到相同字符的位置,情况map,更改下标 public class Solution { /** * @param s: a s
最长无重复字符的子串 Given a string, find the length of the longest substring without repeating characters. Example 1: Input: "abcabcbb" Output: 3 Explanation: The answer is "abc", with the length of 3. Example 2: Input: "bbbbb" Output
Examples: Description: Given a string, find the length of the longest substring without repeating characters. Example: Given "abcabcbb", the answer is "abc", which the length is 3. Given "bbbbb", the answer is "b",
Given a string, find the length of the longest substring without repeating characters. Example 1: Input: "abcabcbb" Output: 3 Explanation: The answer is "abc", with the length of 3. Example 2: Input: "bbbbb" Output: 1 Explana
Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating letters for "abcabcbb" is "abc", which the length is 3. For "bbbbb" the longest subst
Given a string that consists of only uppercase English letters, you can replace any letter in the string with another letter at most k times. Find the length of a longest substring containing all repeating letters you can get after performing the abo
题目: Given a . For . 解题思路: 这个题让找一个字符串中具有不重复单词的最长子串的长度,如:ababc,子串为abc,长度为3.有这么几个方法: 方法一: 依赖字符串本身的一些特有函数,进行相应操作来完成.我们可以维护一个子串,来保存最长的无重复的子串,并记录当前子串的长度,如果遇到重复的字符,则去掉子串中重复的字符,一次进行下去,最终就能找到最长无重复子串.如str = ababc, substr = a, ab, ba, ab, abc....类似这样的思路.如下代码: /
