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 Kotlin (judge verdict: WA: Presentation Error)

const val ELEMENT = "#"

fun main(args: Array<String>) {
    while (true){
        val (h, w) = readLine()?.split(" ")?.map { it.toInt() } ?: return
        if (h == 0 && w == 0) return
        for (i in 0..(h - 1)){
            for (j in 0..(w - 2)){
                print(ELEMENT)
            }
            println(ELEMENT)
        }
    }
}
