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

3 4
5 6
2 2
0 0

Solution in JAVA (judge verdict: Accepted)

//Structured Program I - Print a Rectangle
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

class Main {

	public static void main(String[] args) throws IOException {

		BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

		String input;
		
		 while (!(input = in.readLine()).equals("0 0")) {

			 String[] HW = input.split(" ");

			 int H = Integer.parseInt(HW[0]);
			 int W = Integer.parseInt(HW[1]);

			 for(int i=0;i<H;i++){
				 for(int j=0;j<W;j++){
					 System.out.print("#");
				 }
				 System.out.println();
			 }
			 System.out.println();
			 
		 }

	}
