Welcome to the Factorial in Kotlin page! Here, you'll find the source code for this program as well as a description of how the program works.
import java.math.BigInteger
fun main(args: Array<String>) {
if (args.isNullOrEmpty() || args[0].toIntOrNull()?.takeIf { it >= 0 } == null) {
println("Usage: please input a non-negative integer")
return
}
val num = args[0].toInt()
var factorial = BigInteger.ONE
for (i in 1..num) {
// factorial = factorial * i;
factorial = factorial.multiply(BigInteger.valueOf(i.toLong()))
}
println(factorial)
}
