我的超时思路,感觉自己上了一个新的台阶,虽然超时了,但起码是给出了一个方法. 遍历s 一遍即可,两个指针,当找到了一个合格的字串后,start 开始走,直到遇到s[start]在t中 如果不符合,end++,直到遇到s[end]在t中. class Solution {public: string minWindow(string s, string t) { int start=0,end=t.size()-1; string res; int len=INT_MAX; map<char,in…

7-17 字符串关键字的散列映射(25 分) 给定一系列由大写英文字母组成的字符串关键字和素数P,用移位法定义的散列函数H(Key)将关键字Key中的最后3个字符映射为整数,每个字符占5位:再用除留余数法将整数映射到长度为P的散列表中.例如将字符串AZDEG插入长度为1009的散列表中,我们首先将26个大写英文字母顺序映射到整数0~25:再通过移位将其映射为3×32​2​​+4×32+6=3206:然后根据表长得到,即是该字符串的散列映射位置. 发生冲突时请用平方探测法解决. 输入格式: 输入第…

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…
