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.io.*;

class Main {
	public static void main(String[] args) throws IOException {
		
			BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
			StringBuilder sb=new StringBuilder();
			while (true) {
				String[] cut = br.readLine().split(" ");
				int H = Integer.parseInt(cut[0]);
				int W = Integer.parseInt(cut[1]);
				if (H == 0 && W == 0)
					break;
				for (int j = 0; j < H; j++) {
					for (int i = 0; i < W; i++) {
						sb.append("#");
					}
					sb.append("\n");
				}
				sb.append("\n");
			}
		System.out.print(sb);

	}
