    I cannot pass 2 of the tests with this Kotlin code, anybody has any idea?

    fun main(args: Array<String>) {
    val t = readLine()!!.trim().toInt()

    for (tItr in 1..t) {
        val n = readLine()!!.trim().toInt()
        println("${sumn(n,3)+sumn(n,5)-sumn(n,15)}")
        
    }
    
}

fun sumn(n:Int,d:Int):Int{
    val l = (n-1)/d
    return d*l*(l+1)/2
}
