［抄题］: 给定一个字符串 s 和一个 非空字符串 p ,找到在 s 中所有关于 p 的字谜的起始索引.字符串仅由小写英文字母组成,字符串 s 和 p 的长度不得大于 40,000.输出顺序无关紧要. 样例 给出字符串 s = "cbaebabacd" p = "abc"返回 [0, 6] 子串起始索引 index = 0 是 "cba",是"abc"的字谜. 子串起始索引 index = 6 是 "bac"…
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.…
Find the length of the longest substring T of a given string (consists of lowercase letters only) such that every character in T appears no less than k times. Example 1: Input: s = "aaabb", k = 3 Output: 3 The longest substring is "aaa"…
Given a string s and a non-empty string p, find all the start indices of p's anagrams in s. Strings consists of lowercase English letters only and the length of both strings s and p will not be larger than 40,000. The order of output does not matter.…
Given a string S, find the length of the longest substring T that contains at most two distinct characters.For example:Given S = “eceba”,T is “ece” which its length is 3. 给定字符串S,找到最长子字符串T的长度,最多包含两个不同的字符. 例如: 给定S = “eceba”, T是“ece” ,长度为3. class Soluti…
Given a string, find the length of the longest substring T that contains at most k distinct characters. For example, Given s = "eceba" and k = 2, T is "ece" which its length is 3. 给定一个字符串,找出包含最多k个不同字符的最长子字符串t的长度. 例如,给定s=“eceba”和k=2, T是…
