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

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        ArrayList<Integer> H = new ArrayList<Integer>();
        ArrayList<Integer> W = new ArrayList<Integer>();
        int tempH, tempW;

        while (true) {
            tempH = sc.nextInt();
            tempW = sc.nextInt();

            if (tempH == 0 && tempW == 0)
                break;

            H.add(tempH);
            W.add(tempW);
        }

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

        sc.close();
