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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>
int main()
{
	int A,B,K;
	int Max,Min;
	
	scanf("%d%d%d",&A,&B,&K);
	
	if(B <= K || (A+K) > B) Max = B;
	else Max = A+K-1;
	
	if((A+K) > (B-K)) Min = A+K;
	else Min = B-K+1;
	
	for(int i=A; i <=Max; i++) printf("%d\n",i);
	for(int i=Min; i<=B;i++) printf("%d\n",i);
	
	return 0;
