不好做的一道题,发现String Algorithm可以出很多很难的题,特别是多指针,DP,数学推导的题.参考了许多资料: http://leetcode.com/2010/11/finding-minimum-window-in-s-which.html http://www.geeksforgeeks.org/find-the-smallest-window-in-a-string-containing-all-characters-of-another-string/ http://tia…

leetcode76. Minimum Window Substring 题意: 给定字符串S和字符串T,找到S中的最小窗口,其中将包含复杂度O(n)中T中的所有字符. 例如, S ="ADOBECODEBANC" T ="ABC" 最小窗口为"BANC". 注意: 如果S中没有覆盖T中所有字符的窗口,返回空字符串"". 如果有多个这样的窗口,您可以确保在S中始终只有一个唯一的最小窗口. 思路: 一个right指针遍历s,每次…

一.题目说明 题目76. Minimum Window Substring,求字符串S中最小连续字符串,包括字符串T中的所有字符,复杂度要求是O(n).难度是Hard! 二.我的解答 先说我的思路: (1)统计t中每个字符出现的次数, (2)用hash存储s中出现t中字符的位置, (3)计算最短字符串. 思路有了,惭愧的是,这个题目,我没做出来. 后来参考大神的实现了,用"滑动窗口"实现. 代码如下: class Solution{ public: string minWindow(s…
