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 C# (judge verdict: Wrong Answer)

using System;
using System.Collections.Generic;

class Program {
    static int Main(string[] args) {
        List<int[]> list = new List<int[]>();

        while (true) {
            string v = Console.ReadLine();

            int H = int.Parse(v.Split(' ')[0]);
            int W = int.Parse(v.Split(' ')[1]);
            if ((H == 0) && (W == 0)) { break; }

            list.Add(new int[] { H, W });
        }

        for (int i = 0; i < list.Count; i++) {
        }

        //    List<string> rect = new List<string>();

        //    for (int h = 0; h < list[i][0]; h++) {
        //        Console.Write(new string('#', list[i][1]));
        //        Console.WriteLine("");
        //    }

        //    Console.WriteLine("");
        //}

        return 0;
    }
