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(void)
   {int H[10000], W[10000], i, j, k, l;
    i = 0;
    while(1) {
       scanf("%d %d", &H[i], &W[i]);
       i++;
       if(H[i - 1] == 0 && W[i - 1] == 0)
          break;
    }
    for(j = 0; j < i; i++) {
       for(k = 0; k < H[j] ; k++) {
          for(l = 0; l < W[j]; l++) {
             printf("#");
          }
          printf("\n");
       }
       printf("\n");
    }
    return 0;
