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 Python (judge verdict: WA: Presentation Error)

while True:
    h,w = map(int, raw_input().split())
    
    if h == 0 and w == 0:
        break;
    else:
        r = "#"
        for x in xrange(w-1):
            r = r + "#"
        for x in xrange(h):
	    print r
    print "\n"
