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 such windo…

给定一个字符串 S 和一个字符串 T,找到 S 中的最小窗口,它将包含复杂度为 O(n) 的 T 中的所有字符.示例:S = "ADOBECODEBANC"T = "ABC"最小窗口是 "BANC".注意事项:如果 S 中没有覆盖 T 中所有字符的窗口,则返回空字符串 "".如果有多个这样的窗口,你将会被保证在 S 中总是只有一个唯一的最小窗口.详见:https://leetcode.com/problems/minimum-…

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=…

Given strings S and T, find the minimum (contiguous) substring W of S, so that T is a subsequenceof W. If there is no such window in S that covers all characters in T, return the empty string "". If there are multiple such minimum-length windows…

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…

1. Minimum Window Substring 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 t…
