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

import java.util.Scanner;

class Main {
  public static void main(String args[]){
    long A = 0;
    int B = 0;
    int K = 0;
    Scanner scan = new Scanner(System.in);
    A = scan.nextInt();
    B = scan.nextInt();
    K = scan.nextInt();
    scan.close();
    if((B - A)/2.0 >= K){
    for(int i = 0;i < K; i++){
      System.out.println(A + i);
    }
    for(int i = 0;i < K; i++){
      System.out.println(B - K + i +1);
    }
  }
  else{
    for(int i = 0; i < B - A + 1; i++){
      System.out.println(A + i);
    }
  }
  }
