原题: 438. Find All Anagrams in a String 解题: 两个步骤 1)就是从s中逐步截取p长度的字符串 2)将截取出的字符串和p进行比较,比较可以用排序,或者字典比较(这两种方法提交后都超时了) 代码如下(提交超时): class Solution { public: vector<int> findAnagrams(string s, string p) { int lenp = p.length(); int lens = s.length(); int i=…

Question 438. Find All Anagrams in a String Solution 题目大意:给两个字符串,s和p,求p在s中出现的位置,p串中的字符无序,ab=ba 思路:起初想的是求p的全排列,保存到set中,遍历s,如果在set中出现,s中的第一个字符位置保存到结果中,最后返回结果.这种思路执行超时.可能是求全排列超时的. 思路2:先把p中的字符及字符出现的次数统计出来保存到map中,再遍历s,这个思路和169. Majority Element - LeetCode…
