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

    static void Main(string[] args)
    {
        List<int[]> dataList = new List<int[]>();
        string rs = string.Empty;

        while ((rs = Console.ReadLine()) != "0 0")

            if (rs == null)
                break;

            dataList.Add(rs.Split().Select(int.Parse).ToArray());
        }

        foreach(int[] data in dataList)
        {
            string width = new string('#', data[1]);
            foreach(int height in data)
