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 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int main(void) {
	long A, B;
	int K, s;
	scanf("%ld%ld%d", &A, &B, &K);
	if(A+B-2<2*K)
	{for(s=A;s<=B;s++)
	printf("%d \n", s);
	}
	else
	{
	for(s =A;s<A+K&&s<=B;s++)
	{printf("%d \n",s);}
	for(s=B-K+1;s<=B;s++)
	{printf("%d \n",s);}
	}
	return 0;
