Grid markup is a process, where each of the grid cells is marked with a star symbol $\texttt{*}$.

Your task is very simple. You are given a grid height and weight and the output is the markup grid with the star symbol $\texttt{*}$.

## Input

Input starts with an integer $T$ ($1 \le T \le 20$), the number of test cases. Each of the following $T$ lines contains two integers $H$ and $W$ denoting the height and weight respectively. Here $2 \le H \le 30$ and $2 \le W \le 30$.

## Output

For each test case, print the test case serial on a line, followed by the markup grid as described in the problem statement.
