Problem A

Statement
Copy Copied
Description:
You are given an integer $$$n$$$.

Your task is to build a string of uppercase Latin letters. There must be exactly $$$n$$$ special characters in this string. Let's call a character special if it is equal to exactly one of its neighbors.

For example, there are $$$6$$$ special characters in the AAABAACC string (at positions: $$$1$$$, $$$3$$$, $$$5$$$, $$$6$$$, $$$7$$$ and $$$8$$$).

Print any suitable string or report that there is no such string.

Input Format:
The first line contains a single integer $$$t$$$ ($$$1 \le t \le 50$$$) — the number of test cases.

The only line of each test case contains a single integer $$$n$$$ ($$$1 \le n \le 50$$$).

Output Format:
For each test case, print the answer as follows:

- if there is no suitable string, print one line containing the string NO;
- otherwise, print two lines. The first line should contain the string YES; on the second line print a string of length at most $$$200$$$ — the answer itself (it can be shown that if some answers exist, then there is an answer of length at most $$$200$$$). If there are several solutions, print any of them.

Note:
None
