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)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;

class Main {

	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String strNum = "";
		ArrayList<String> squea = new ArrayList<String>();
		while (true) {
			strNum = br.readLine();
			if ("0 0".equals(strNum)) {
				break;
			}
			for (int i = 0; i < Integer.parseInt(strNum.split(" ")[0]); i++) {
				String line = "";
				for (int j = 0; j < Integer.parseInt(strNum.split(" ")[1]); j++) {
					line += "#";
				}
				squea.add(line);
			}
			squea.add("");
		}
		for (int i = 0; i < squea.size(); i++) {
			System.out.println(squea.get(i));
		}
	}
