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.

Sample Input 1

3 8 2

Sample Output 1

3
4

Solution in Go (1.6) (judge verdict: Runtime Error)

package main

import (
	"fmt"
)

func main() {
	var a,b,k int
	fmt.Scan(&a,&b,&k)
	
	nums := make([]int, b-a+1)
	
	input := a
	for i := 0; i < len(nums); i++ {
		nums[i] = input
		input++
	}
	
	
	if b - a + 1 <= k * 2 {
		for i := 0; i < len(nums); i++{
			fmt.Println(nums[i])
		}
	} else {
		for i := 0; i < k; i++ {
			fmt.Println(nums[i])
		}
		for i := len(nums)-k; i < len(nums); i++ {
			fmt.Println(nums[i])
		}
	}
