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 max(int x,int y){
	if(x>y)return x;
	return y;
}


int main(){
	int A,B,K,i;
	scanf("%d%d%d",&A,&B,&K);
	for(i=A;i<=B && i<A+K;i++)printf("%d\n",i);
	for(i=max(i+1,B-K+1);i<=B;i++)printf("%d\n",i);
	return 0;
}
