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

Solution in C# (judge verdict: Accepted)

using System;

namespace ITP1_5_A{
    class Rectangle{
        static void Main(string[] args){
            int h,w;
            string[] arr;
            while(true){
                arr = Console.ReadLine().Split(' ');
                h = int.Parse(arr[0]);
                w = int.Parse(arr[1]);
                if((h==0)&&(w==0)) break;
                for(int i=0; i<h; i++){
                    for(int j=0; j<w; j++){
                        Console.Write("#");
                    }
                    Console.WriteLine();
                }
                Console.WriteLine();
            }
        }
