Hey guys, this is my solution to the easy level Leetcode anagram problem. 一种思路是不断移动大小为t.length()的window，如果当前window中的字符统计和target一样，就放入结果中。, 通用Sliding Window 模板可以解决：counter记录map中还需要match的字符个数，如果counter==0，说明当前window中substring包含了要找的target string anagram，但是可以进一步检测是否可以缩短这个window。通过调整begin来实现。所以这个sliding window其实window size是在变化的，只有当counter==0，并且当前window size: end - begine == t.length()时，才记录结果。.
