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 h,w,i,j;
  scanf("%d %d",&h,&w);
  while(1){
    if (h==0 && w ==0)
      break;
    else{
      for(i=0;i<=h-1;i++){
	for (j=0;j<=w-1;j++){
	  printf("#");}
	printf("\n");
      }
      printf("\n");
    }
  }
  return 0;
