Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Sample Input

3 4
5 6
2 2
0 0

		int i=0;
		
		while(true){
			h[i]=kb.nextInt();
			w[i]=kb.nextInt();

			i++;
		}
		i=0;
		
		for(int a=0;a<h.length-1;a++){
