Given a stringS, return the number of substrings of lengthKwith no repeated characters. Example 1: Input: S ="havefunonleetcode", K =5 Output:6 Explanation: There are 6 substrings they are : 'havef','avefu','vefun','efuno','etcod','tcode'. ...
Actually we can get the class of an array by using the following code: int[]arr=newint[3];System.out.println(arr.getClass()); Output: class [I “class [I” stands for the run-time type signature for the class object “array with component type int”. ...

Given"pwwkew", the answer is"wke", with the length of 3. Note that the answer must be a substring,"pwke"is asubsequenceand not a substring. 翻译 给定一个字符串,找到最长的子串的长度,这个子串不存在重复的字符。 例如: 输入”abcabcbb”, 符合条件的子串就是”abc”, 长度为3。
那么如果将数组换成字符串,实际这道题就是求 Longest Common Substring 的问题了,而貌似 LeetCode 上并没有这种明显的要求最长相同子串的题,注意需要跟最长子序列 Longest Common Subsequence 区分开,关于最长子序列会在 follow up 中讨论。好,先来看这道题,既然是子数组,那么重复的地方一定是连续的,而且起点可能...
