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

Solution in JAVA (judge verdict: Accepted)

		import java.util.Scanner;
public class Main {
	public static void main(String[] args) {
		Scanner sc=new Scanner(System.in);
StringBuilder sb=new StringBuilder("");
		int H=sc.nextInt(),W=sc.nextInt();
		while (H!=0 || W!=0){
			for (int m=1;m<=W;m++){
			sb.append("#");}
		for (int n=1;n<=H;n++){System.out.println(sb);}
			System.out.println();
			sb.delete(0,W);
			H=sc.nextInt();W=sc.nextInt();
