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.

Solution in Java (OpenJDK 11.0.6) (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {

	private static final long x = (long) Math.pow(10, 18);

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

		for (int i = a; i < a + k; i++) {
			System.out.println(i);
		}

		for (int i = b; b - k < i; i--) {
			System.out.println(i);
		}

		sc.close();
	}
