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

		int a = scn.nextInt();
		int b = scn.nextInt();
      	int k = scn.nextInt();
      	if(k>(a+b)/2-a){
        	for(int i=0; i<b-a+1; ++i){
				System.out.println(a+i);
			}
        }else if(a==b){
