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

class Program
{
	static void Main(string[] args)
	{
		var line = 0;
		while(true){
			string[] str = Console.ReadLine().Split();
			int H = int.Parse(str[0]);
			int W = int.Parse(str[1]);
			if(H==0 && W==0){
				break;
			}
			if(line >= 1){
				Console.WriteLine("");
			}
			line += 1;
			for(var i=0;i<H;i++){
				string s = "";
				for(var j=0;j<W;j++){
					s += "#";
				}
				Console.WriteLine(s);
