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

Solution in Scala (2.11.7) (judge verdict: Wrong Answer)

object Main extends App {
  val sc = new java.util.Scanner(System.in)
  val A = sc.nextInt
  val B = sc.nextInt
  val K = sc.nextInt

  // AからA+Kまで出力(ただしBを超えたら終わり)
  for (i <- A to A + K) {
    if (i <= B) {
      println(i)
    }
  }

  // B-KからBまで出力(ただし、A+K以上である必要がある)
  for (j <- B-K to B) {
    if (j > A + K) {
      println(j)
    }
  }
}
