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 Kotlin (1.3.71) (judge verdict: Accepted)

fun main(arr: Array<String>) {
    val inpt = readLine()!!.split(" ").map { it.toLong() }
    var ab = inpt.take(2).toMutableList()
    val k = inpt[2].toInt()
    for(i in (0 until k)) {
        val idx1 = i%2
        val idx2 = (idx1+1)%2

        if(ab[idx1]%2!=0L) {
            ab[idx1]--
        }
        ab[idx2] += ab[idx1]/2
        ab[idx1] = ab[idx1]/2
    }
    println(ab.joinToString(" "))
}
