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

        Scanner sc = new Scanner(System.in);
        long A = sc.nextLong();
        long B = sc.nextLong();
        int K = sc.nextInt();
        if(2*K>=(B-A+1)){
            for(long i=A;i<=B;i++){
                System.out.println(i);
            }
        }
        else{
            for(long i=A;i<A+K;i++){
                System.out.println(i);
            }
            for(long i=B-K+1;i<=B;i++){
                System.out.println(i);
            }
        }
        //System.out.println(ans);
    }
