Problem Statement

Print all the integers that satisfies the following in ascending order:

Among the integers between A and B (inclusive), it is either within the K smallest integers or within the K largest integers.

Constraints

1 \leq A \leq B \leq 10^9

1 \leq K \leq 100

All values in input are integers.

Input

Input is given from Standard Input in the following format:

A B K

Output

Print all the integers that satisfies the condition above in ascending order.

Solution in Scala (2.11.7) (judge verdict: Runtime Error)

import java.util.Scanner

object Main {
  def main(args: Array[String]): Unit = {
    val sc: Scanner = new Scanner(System.in)
    val Array(a, b, k) = sc.nextLine.split(" ").map(_.toInt)
    val targetArray = (a to b).toArray
    val fromTop = targetArray.slice(0, Array(k, targetArray.length).min)
    val fromLast = targetArray.reverse.slice(0, Array(k, targetArray.length).min)

    (fromTop ++ fromLast).distinct.sorted.map(println(_))
  }
