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

import java.util.Scanner;

public class Main {

  public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);
    int a = sc.nextInt();
    int b = sc.nextInt();
    int k = sc.nextInt();

    if (((a + k) - 1) >= ((b - k) + 1)) {
      for (int i = a; i <= b; i++) {
        System.out.println(i);
      }
    } else {
      for (int i = a; i <= ((a + k) - 1); i++) {
        System.out.println(i);
      }
      for (int i = (b - k) + 1; i <= b; i++) {
        System.out.println(i);
      }
    }
