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

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.*;

class Main{
  public static void main(String[] args){

    Scanner sc = new Scanner(System.in);

    int A = sc.nextInt(); // A <= 10^9
    int B = sc.nextInt(); // B <= 10^9
    int K = sc.nextInt(); // K <= 100

    if(2 * K  <= B - A  ){
      for(int i = 0 ; i < K ; i ++ ){
        System.out.println(A + i);
      }
      for(int i = K - 1 ; i >= 0  ; i -- ){
        System.out.println(B - i);
      }
    } else {
      for(int i = 0 ; i < B - A + 1;i ++ ){
        System.out.println(A + i);
      }
    }
  }
}
