Solution in Kotlin (judge verdict: Accepted)

fun main(arg: Array<String>) {
    while(true) {
        val (h, w) = readLine()!!.split(" ").map(String::toInt)
        if (h == 0 && w == 0) break
        for (i in 1..h) {
            for (j in 1..w) {
                print("#")
            }
            println("")
        }
        println("")
    }
