C语言 · Anagrams问题

问题描述

　　Anagrams指的是具有如下特性的两个单词：在这两个单词当中，每一个英文字母（不区分大小写）所出现的次数都是相同的。例如，“Unclear”和“Nuclear”、“Rimon”和“MinOR”都是Anagrams。编写一个程序，输入两个单词，然后判断一下，这两个单词是否是Anagrams。每一个单词的长度不会超过80个字符，而且是大小写无关的。
　　输入格式：输入有两行，分别为两个单词。
　　输出格式：输出只有一个字母Y或N，分别表示Yes和No。
　　输入输出样例

样例输入

Unclear
Nuclear

样例输出

Y

 

 

 /*
     思路：都转换成小写，在长度相等的情况下，
           分别遍历记录下每个字母出现的次数。
           最后比较各个数字是否相等。

     字符串数组长度：100 ——单词长度不会超过80。
