Right shift a given string by n characters. Assumptions The given string is not null. n >= 0. Examples "abc", 4 -> "cab" public class Solution { public String rightShift(String input, int n) { // Write your solution here if (inpu…

Given a string, find the longest substring without any repeating characters and return the length of it. The input string is guaranteed to be not null. For example, the longest substring without repeating letters for "bcdfbd" is "bcdf"…

题目描述 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…

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"…

创建shift粘滞键后门: 1 c: 2 3 cd \Windows\System32\ 4 5 rename sethc.exe bak_sethc.exe 6 7 xcopy cmd.exe sethc.exe 8 9 exit 恢复原状态: c: cd \Windows\System32\ del sethc.exe rename bak_sethc.exe sethc.exe exit…

今天本来运行了打算这样的方法 arguments.shift() (shift方法是删除数组的第一个元素,例如var arr=[1,2,3,4,5]执行var a=arr.shift();之后,a的值为1,arr的值为[2,3,4,5].) 参考w3cschool:http://www.w3school.com.cn/jsref/jsref_shift.asp 在IDEA中居然还有这样的代码提示 结果抛出了这样的异常 原来是arguments不是真正的数组,不支持shift, 不过我们可以从支持…

Given a string, sort it in decreasing order based on the frequency of characters. Example 1: Input: "tree" Output: "eert" Explanation: 'e' appears twice while 'r' and 't' both appear once. So 'e' must appear before both 'r' and 't'. Th…

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. 这道题是之前那道Longest Substring with At Most Two Distinct Characters的拓展…

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. 这道题给我们一个字符串,让我们求最多有两个不同字符的最长子串.那么我们首先想到的是用哈希表来做,哈希表记录每个字符的出现次数,然后如果哈希表中的映射数量超过两…
