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 PHP (5.6.30) (judge verdict: Wrong Answer)

<?php
fscanf(STDIN,'%d%d%d',$A,$B,$K);
if($A==$B){
   echo $A;
}elseif($A+$K-1<=$B-$K+1){
  for ($i=$A; $i <=$A+$K-1 ; $i++) {
    // code...
    echo $i;
    echo "\n";
  }
  for ($i=$B-$K+1; $i <=$B ; $i++) {
    // code...
    echo $i;
    echo "\n";
  }
}else{
  for ($i=$A; $i <=$B ; $i++) {
    // code...
    echo $i;
    echo "\n";
  }
}
