Problem Statement

M-kun is a competitor in AtCoder, whose highest rating is X.

In this site, a competitor is given a kyu (class) according to his/her highest rating. For ratings from 400 through 1999, the following kyus are given:

From 400 through 599: 8-kyu

From 600 through 799: 7-kyu

From 800 through 999: 6-kyu

From 1000 through 1199: 5-kyu

From 1200 through 1399: 4-kyu

From 1400 through 1599: 3-kyu

From 1600 through 1799: 2-kyu

From 1800 through 1999: 1-kyu

What kyu does M-kun have?

import java.util.*

fun main(args: Array<String>) {
    val scan = Scanner(System.`in`)
    var kotlin=scan.nextLine().toInt()
    if(kotlin>=400 && kotlin<=599)
        println("8")
    if(kotlin>=600 && kotlin<=799)
        println("7")
    if(kotlin>=800 && kotlin<=999)
        println("6")
    if(kotlin>=1000 && kotlin<=1199)
        println("5")
    if(kotlin>=1200 && kotlin<=1399)
        println("4")
    if(kotlin>=1400 && kotlin<=1599)
        println("3")
    if(kotlin>=1600 && kotlin<=1799)
        println("2")
    if(kotlin>=1800 && kotlin<=1999)
