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

#include <stdio.h>
int main(){
	int a,b,c[300],d[300],i,j,k=0,l;

	while(1){
		scanf("%d %d",&a,&b);
		if(a==0 && b==0)
			break;
		c[k]=a;
		d[k]=b;
		k++;
	}
	for(l=0;l<=k;l++){
		for(i=0;i<c[l];i++){
			for(j=0;j<d[l];j++){
				printf("#");
			}
			printf("\n");
		}
		printf("\n");
	}
	return 0;
