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 C# (Mono 4.6.2.0) (judge verdict: Wrong Answer)

using System;
class p
{
  static void Main()
  {
    string[] input = Console.ReadLine().Split(' ');
    int A = int.Parse(input[0]);
    int B = int.Parse(input[1]);
    int K = int.Parse(input[2]);
    
    if (K * 2 < B - A) {
      for (int i = A; i < A + K; i++) {
        Console.WriteLine(i);
      }
      for (int i = B - (K - 1); i <= B; i++) {
        Console.WriteLine(i);
      }
    } else {
      for (int i = A; i <= B; i++) {
        Console.WriteLine(i);
      }
    }
  }
}
