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.*;

      long    K    = scan.nextInt();
      long    u    = 0;

      if((B - A) <= K){
         for(long i = A; i <= B; i++){
             System.out.println(i);
             }
         }
      else{
          for(long i = A; i < A + K; i++){
              System.out.println(i);
              }
          for(long i = Math.max(A + K, B - K + 1); i <= B; i++){
              System.out.println(i);
              }
          }
