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

Solution in C (judge verdict: Time Limit Exceeded)

#include <stdio.h>

int main(void)
{
int H, W, i, j, k;

i = 0;
j = 0;
k = 0;

while(1){
scanf("%d %d", &H, &W);

if(H == 0 && W == 0)break;
for(k = 0; k <= H; k++) {
for(i = 0; i < H; i++){
  for(j = 0; j < H; i++){
  printf("#");
  }
printf("\n ");
}
printf("\n ");
}
}
return 0;
