Can you solve this real interview question? Longest Substring Without Repeating Characters - Given a string s, find the length of the longest substring without duplicate characters. Example 1: Input: s = "abcabcbb" Output: 3 Explanation: The answer
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 ...
Leetcode 3. Longest Substring Without Repeating Characters,题意:求字符串中的最长非重复子串思路:用O(n)即可要求知道每次字符的上一次出现的位置例如0 1 2 3 4 5a a b c b c首先
Can you solve this real interview question? Longest Substring Without Repeating Characters - Given a string s, find the length of the longest substring without duplicate characters. Example 1: Input: s = "abcabcbb" Output: 3 Explanation: The answer
解释: 因为无重复字符的最长子串是 "abc",所以其长度为 3。 示例2: 输入: "bbbbb" 输出: 1 解释: 因为无重复字符的最长子串是 "b",所以其长度为 1。 示例3: 输入: "pwwkew" 输出: 3 解释: 因为无重复字符的最长子串是 "wke",所以其长度为 3。
