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.

Sample Input 1

3 8 2

Sample Output 1

import java.util.*;
public class Main {
	//定義関数から参照できる変数定義はこの辺
	static int A;
	static int B;
	static int K;
	static int ans=0;


	public static void main(String[] args) {
    	Scanner sc = new Scanner(System.in);
		A = sc.nextInt();
		B = sc.nextInt();
		K = sc.nextInt();

		if ((A+K-1)<(B-K+1)) {
			for(int i=A;i<=A+K-1;i++){
				ans=i;
				System.out.println(ans);
			}
			for(int i=B-K+1;i<=B;i++){
				ans=i;
				System.out.println(ans);
			}
		}
		else{
			for(int i=A;i<=B;i++){
				ans=i;
				System.out.println(ans);
			}

		}


		
		//System.out.print(ans);
    }
