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 (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>

int main()
  {
      char a,b,c;
   
      scanf("%c", &a);
      scanf("%c", &b);
      scanf("%c", &c);
   
      if((a == 'a' && b == 'b' && c == 'c') || (a == 'a' && b == 'b' && c == '    c') || (a == 'b' && b == 'a' && c == 'c') || (a == 'b' && b == 'c' && c == '    a') || (a == 'c' && b == 'a' && c == 'b') || (a == 'c' && b == 'b' && c == '    a')) {
          printf("Yes\n");
      }
      else
          printf("No\n");
   
      return 0;
  }
