Current Solution
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 )
}
