CF43B.Letter

Vasya decided to write an anonymous letter cutting the letters out of a newspaper heading. He knows heading _s_1 and text _s_2 that he wants to send. Vasya can use every single heading letter no more than once. Vasya doesn't have to cut the spaces out of the heading — he just leaves some blank space to mark them. Help him; find out if he will manage to compose the needed text.

瓦西娅决定写一封匿名信，他打算从报纸标题中剪下字母来拼凑信件内容。他已知标题字符串 $s_1$ 和他想要发送的文本字符串 $s_2$。瓦西娅最多只能使用标题中的每个字母一次。瓦西娅无需从标题中剪下空格——他只需在相应位置留出空白即可表示空格。请帮助他判断：他能否成功拼凑出所需的文本？

The first line contains a newspaper heading _s_1. The second line contains the letter text _s_2. _s_1 и _s_2 are non-empty lines consisting of spaces, uppercase and lowercase Latin letters, whose lengths do not exceed 200 symbols. The uppercase and lowercase letters should be differentiated. Vasya does not cut spaces out of the heading.

第一行包含报纸标题 $s_1$。第二行包含信件正文 $s_2$。$s_1$ 和 $s_2$ 是非空字符串，仅由空格、大小写拉丁字母组成，长度均不超过 200 个字符。大小写字母需区分。瓦夏不会从标题中删除空格。

If Vasya can write the given anonymous letter, print YES, otherwise print NO

如果瓦西娅能写出给定的匿名信，则输出 YES，否则输出 NO
