Simple Palindrome

Narek has to spend 2 hours with some 2-year-old kids at the kindergarten. He wants to teach them competitive programming, and their first lesson is about palindromes.

Narek found out that the kids only know the vowels of the English alphabet (the letters a, e, i, o, and u), so Narek needs to make a string that consists of vowels only. After making the string, he'll ask the kids to count the number of subsequences that are palindromes. Narek wants to keep it simple, so he's looking for a string such that the amount of palindrome subsequences is minimal.

Help Narek find a string of length nn, consisting of lowercase English vowels only (letters a, e, i, o, and u), which minimizes the amount of palindrome^{\dagger} subsequences^{\ddagger} in it.

^{\dagger} A string is called a palindrome if it reads the same from left to right and from right to left.

^{\ddagger} String tt is a subsequence of string ss if tt can be obtained from ss by removing several (possibly, zero or all) characters from ss and concatenating the remaining ones, without changing their order. For example, odocs is a subsequence of c}{\color{red}{\texttt{od}}}\texttt{ef}{\color{red}{\texttt{o}}}\texttt{r}{\color{red}{\texttt{c}}}\texttt{e}{\color{red}{\texttt{s}}.

Input

The first line of the input contains a single integer tt (1t1001 \le t \le 100) — the number of test cases. Subsequently, the description of each test case follows.

The only line of each test case contains a single integer nn (1n1001 \le n \le 100) — the size of the string.

Output

For each test case, output any string of length nn that satisfies the above conditions.

Note

In the first example, uo has only three palindrome subsequences: u, o, and the empty string. It can be shown that there is no better answer.

In the third example, oeiiua has only eight palindrome subsequences: o, e, i, i, u, a, ii, and the empty string. It can be shown that there is no better answer.
