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(){
  int H,W,i,j;
  scanf("%d %d\n",&H,&W);
  while(1){
    if(H==0 && W==0)break;
    if(H>300 || W>300)break;
  for(j=0;j<H;j++){
    if(H==0 && W==0)break;
      for(i=0;i<W;i++){
	printf("#");
      }
      printf("\n");
  }
  }     
  return 0;
