Custom Sort String Solution 题目大意:给你字符的顺序,让你排序另一个字符串。 思路: Java实现: 转载于:https://my.oschina.net/yysue/blog/1933193...Leetcode 791. 自定义字符串排序 791. Custom Sort String 791. 自定义字符串排序 字符串S和 T 只包含小写字符。在S中,所有字符只会出现一次。 S ...
LeetCode-Custom Sort String Description: S and T are strings composed of lowercase letters. In S, no letter occurs more than once. S was sorted in some custom order previously. We want to permute the characters of T so that they match the order that S was sorted. More specifically, if ...

1 先统计T中字母出现的次数,然后遍历S中的所有字母,如果S中的字母有出现在T中,则拿出来放在结果中,最后再将没出现在S中的字符添加在末尾 2 可以使用python自带的OrderedDict 3 老是忘记string本身自带的count函数 4 return的是string,但我们可以先定义成list,最后再转成string,方便操作...

Leetcode791 Custom Sort String Java实现 因为之前的做的几道String的题感觉都是在让熟悉javase的String相关API,于是看到这题首先就想到了Arrays.sort方法,实现一个comparator从而实现比较,后来发现这个方法比较笨,也没有必要,运行速度也慢,时间复杂度大概在O(nlogn)(快排),但是想想这个方法还是有必要会用的,于是就...
