- Microsoft Q#

Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ACM-ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.
Never use someone else's code, read the tutorials or communicate with other person during a virtual contest.

standard outputImplement a quantum oracle on *N* qubits which implements the following function: , i.e., the value of the function is 1 if *x* has odd number of 1s, and 0 otherwise.

Input

You have to implement an operation which takes the following inputs:

- an array of qubits
*x*(input register), - a qubit
*y*(output qubit).

The operation doesn't have an output; the "output" of your solution is the state in which it left the qubits.

Your code should have the following signature:

namespace Solution {

open Microsoft.Quantum.Primitive;

open Microsoft.Quantum.Canon;

operation Solve (x : Qubit[], y : Qubit) : ()

{

body

{

// your code here

}

}

}
