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;
class Main {
	int W = 0,H = 0,I = 0,F = 0;
	public void pr() {
		Scanner sc = new Scanner(System.in);
		H = sc.nextInt();
		W = sc.nextInt();
		while(H != 0 || W != 0) {
			for(I = 0;I < H; I++) {
				for(F = 0;F < W; F++) {
					System.out.print("#");
					if(F == W-1) {
						System.out.println();
					}
				}
			}
				System.out.println();
			H = sc.nextInt();
			W = sc.nextInt();
		}
	}
	public static void main(String[] args) {
		new Main().pr();
	}
