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

	int H,M;
	
	scanf("%d %d",&H, &M);
	
	int h,m;
	
	while(1){
		
		if( H == 0 && M == 0 ){
			break;
		}
		
		for(h = 0; h < H; h++)
		{
			for(m = 0; m < M; m++)
			{
			
				printf( "#" );

			printf( "\n" );
		}
	}
	
	return 0;
