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 Kotlin (judge verdict: Accepted)

fun main(args: Array<String>) {
    while (true) {
        val inStr = readLine()
        val (h, w) = inStr?.split(' ')?.map { s -> s.toInt() } ?: return

        if ((h == 0) && (w == 0)) {
            return
        }
        printRectangle(h, w)
    }
}

fun printRectangle(height:Int, width:Int) {
    val line = "#".repeat(width)
    val rectAngle = (line + "\n").repeat(height)
    println(rectAngle)
}
