问题描述:给定字符串S,子串T,求S中包含T的最小窗口 Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n). For example,S = "ADOBECODEBANC"T = "ABC" Minimum window is "BANC". 算法分析:
String Problem Description Give you a string with length N, you can generate N strings by left shifts. For example let consider the string “SKYLONG”, we can generate seven strings: String Rank SKYLONG 1 KYLONGS 2 YLONGSK 3 LONGSKY 4 ONGSKYL 5 NGSKYLO
Alyona's mother wants to present an array of n non-negative integers to Alyona. The array should be special. Alyona is a capricious girl so after she gets the array, she inspects m of its subarrays. Subarray is a set of some subsequent elements of th
Given a string s, partition s such that every substring of the partition is a palindrome. Return the minimum cuts needed for a palindrome partitioning of s. For example, given s = "aab", Return 1 since the palindrome partitioning ["aa"

问题: Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. 官方难度: Medium 翻译: 给定一个字符串S,找出最长回文子串,你可以假定字符串的最大长度为1000,并且只有一个最长回文子串. 例子:
LeetCode:Palindrome Partitioning 题目如下:(把一个字符串划分成几个回文子串,枚举所有可能的划分) Given a string s, partition s such that every substring of the partition is a palindrome. Return all possible palindrome partitioning of s. For example, given s = "aab",Return [ [
找出包含子串的最小窗口 Given a string S and a string T, find the minimum window in S which will contain all the characters in T in complexity O(n). For example,S = "ADOBECODEBANC"T = "ABC" Minimum window is "BANC". Note:If there is no s
Problem Description 最后的挑战终于到了!站在yifenfei和MM面前的只剩下邪恶的大魔王lemon一人了!战胜他,yifenfei就能顺利救出MM.Yifenfei和魔王lemon的挑战很简单:由lemon给出三个字符串,然后要yifenfei说出第一串的某个子串,要求该子串长度最小,并且同时包含第2个串和第3个串.特别地,如果有多个这样的子串,则请输出字母序最小的一个. Input 输入数据首先是一个整数C,表示测试数据有C组:接着是C组数据,每组包含三行字符串,第一
