Description
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).
