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

#include <stdio.h>
int main(void){
    int i,j,H,W;
    
    for(;;) {
        scanf("%d %d", &H, &W);
            for(i = 0; i < H; i++){
                for(j = 0; j < W; j++){
                    printf("#");
                }
            if(H==0 || W==0){
                break;
            }
        printf("\n");
            }
    }
    
return 0;
