Problem A

Statement
Copy Copied
Description:
Team Red and Team Blue competed in a competitive FPS. Their match was streamed around the world. They played a series of $$$n$$$ matches.

In the end, it turned out Team Red won $$$r$$$ times and Team Blue won $$$b$$$ times. Team Blue was less skilled than Team Red, so $$$b$$$ was strictly less than $$$r$$$.

You missed the stream since you overslept, but you think that the match must have been neck and neck since so many people watched it. So you imagine a string of length $$$n$$$ where the $$$i$$$-th character denotes who won the $$$i$$$-th match  — it is R if Team Red won or B if Team Blue won. You imagine the string was such that the maximum number of times a team won in a row was as small as possible. For example, in the series of matches RBBRRRB, Team Red won $$$3$$$ times in a row, which is the maximum.

You must find a string satisfying the above conditions. If there are multiple answers, print any.

Input Format:
The first line contains a single integer $$$t$$$ ($$$1 \le t \le 1000$$$)  — the number of test cases.

Each test case has a single line containing three integers $$$n$$$, $$$r$$$, and $$$b$$$ ($$$3 \leq n \leq 100$$$; $$$1 \leq b < r \leq n$$$, $$$r+b=n$$$).

Output Format:
For each test case, output a single line containing a string satisfying the given conditions. If there are multiple answers, print any.

Note:
The first test case of the first example gives the optimal answer for the example in the statement. The maximum number of times a team wins in a row in RBRBRBR is $$$1$$$. We cannot minimize it any further.

The answer for the second test case of the second example is RRBRBRBRBR. The maximum number of times a team wins in a row is $$$2$$$, given by RR at the beginning. We cannot minimize the answer any further.
