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.

import java.util.*;

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 == B){
		    System.out.println(A);
		}else{

		    if(K > B){
			K = B - A;
		    }

		    for(int i = A; i < A + K; i++){
			if(i > B){break;}
			System.out.println(i);
		    }

		    int l = B - A + 1;
		    if (K * 2 > l){
			K = l - K;
		    }
		    
		    for(int j = B - K + 1; j < B + 1; j++){	    
			System.out.println(j);
		    }

		}
	}
