题目描述:
输入一个字符串,请判断这个字符串是不是字符串 Timur
的一种排列。
例如:Timur
,miurT
,Trumi
,mriTu
都是正确的排列。
注意:正确的排列必须包含大写的T和小写的其他字母。
输入格式:
输入的第一行一个整数 ttt ,表示有 ttt 组数据。
对于每组数据,第一行一个整数 nnn,表示输入的名字排列的长度。
第二行一个字符串,表示需要判断的排列。
输出格式:
对于每组数据,如果当前排列事是正确的,则输出 YES

数据范围和约定
$ 1 \le t \le 10^3 $ , 1≤n≤101 \le n \le 101≤n≤10。

Timur likes his name. As a spelling of his name, he allows any permutation of the letters of the name. For example, the following strings are valid spellings of his name: Timur, miurT, Trumi, mriTu. Note that the correct spelling must have uppercased T and lowercased other letters.
Today he wrote string $ s $ of length $ n $ consisting only of uppercase or lowercase Latin letters. He asks you to check if $ s $ is the correct spelling of his name.
The first line of the input contains an integer $ t $ ( $ 1 \leq t \leq 10^3 $ ) — the number of test cases.
The first line of each test case contains an integer $ n $ $ (1 \leq n \leq 10) $ — the length of string $ s $ .
The second line of each test case contains a string $ s $ consisting of only uppercase or lowercase Latin characters.
For each test case, output “YES” (without quotes) if $ s $ satisfies the condition, and “NO” (without quotes) otherwise.
You can output the answer in any case (for example, the strings “yEs”, “yes”, “Yes” and “YES” will be recognized as a positive answer).
