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). Example: Input: S = "ADOBECODEBANC", T = "ABC" Output: "BANC" Note: If there is no such window in S…

原题地址 用两个指针分别记录窗口的左右边界,移动指针时忽略那些出现在S种但是没有出现在T中的字符 1. 扩展窗口.向右移动右指针,当窗口内的字符即将多于T内的字符时,停止右移 2. 收缩窗口.向右调整左指针,当窗口内的字符即将少于T内的字符时,停止右移 3. 统计结果.如果窗口内的字符包含了T内的所有字符,且窗口更小,更新最小窗口 4. 继续下一个周期(返回1) 大致思路就是这样了,在具体实现中我用了一个left变量记录当前还未完全包含的非重字符数量,比如当前窗口还差2个a和3个b,则left=…

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…
