Problem Statement

In the beginning, Takahashi has A cookies, and Aoki has B cookies.
They will perform the following operation alternately, starting from Takahashi:

If the number of cookies in his hand is odd, eat one of those cookies; if the number is even, do nothing. Then, give one-half of the cookies in his hand to the other person.

Find the numbers of cookies Takahashi and Aoki respectively have after performing K operations in total.

Constraints

1 \leq A,B \leq 10^9

1 \leq K \leq 100

A,B and K are integers.

Input

Input is given from Standard Input in the following format:

A B K

Output

Print the number of cookies Takahashi has, and the number of cookies Aoki has, in this order, after performing K operations in total.

Sample Input 1

5 4 2

Sample Output 1

5 3

The process will go as follows:

In the beginning, Takahashi and Aoki have 5 and 4 cookies, respectively.

Takahashi eats one cookie and gives two cookies to Aoki. They now have 2 and 6 cookies, respectively.

Aoki gives three cookies to Takahashi. They now have 5 and 3 cookies, respectively.

Sample Input 2

3 3 3

Sample Output 2

1 3

Sample Input 3

314159265 358979323 84

Sample Output 3

448759046 224379523

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;

public class AtCoder{
	public static void Main(){
		string[] s;
		s = Console.ReadLine().Trim().Split(' ');
		
		int a,b,k;
		a = int.Parse(s[0]);
		b = int.Parse(s[1]);
		k = int.Parse(s[2]);
		
		for (int i=0; i<k; i++){
			if(i%2==0){
				if(a%2==1) a--;
				b = b + a/2;
				a = a/2;
			}else{
				if(b%2==1) b--;
				a = a + b/2;
				b = b/2;
			}
		}
		Console.WriteLine(a+" "+b);
	}
