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

using System;

namespace ITP1_5_A {
    class Program {
        static void Main(string[] args) {
            while(true) {
                string[] s = Console.ReadLine().Split(' ');
                int H = int.Parse(s[0]), W = int.Parse(s[1]);
                if(H == 0 && W == 0) break;
                for(int i = 0; i < H; i++) {
                    for(int u = 0; u < W; u++) {
                        Console.Write("#");
                        if(u == W - 1) Console.Write("\n");
                    }
                }
                Console.Write("\n");
            }
