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 JavaScript (Node.js 12.16.1) (judge verdict: Accepted)

const main = stdin => {
  const input = stdin.trim().split('\n')
  const [A, B, K] = input[0].split(' ').map(x => parseInt(x))

  for (let i = A; i <= B; i++) {
    if (i < A + K || i > B - K) {
      console.log(i);
    }
  }
}

main(require("fs").readFileSync("/dev/stdin", "utf8"))
