OR oracle

Implement a quantum oracle on $$$N$$$ qubits which implements the following function: $$$$$$f(\vec{x}) = x_0 \vee x_1 \vee \dotsb \vee x_{N-1}$$$$$$

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

• an array of $$$N$$$ ($$$1 \le N \le 8$$$) qubits $$$x$$$ in an arbitrary state (input register),
• a qubit $$$y$$$ in an arbitrary state (output qubit),

and performs a transformation $$$|x\rangle|y\rangle \rightarrow |x\rangle|y \oplus f(x)\rangle$$$. The operation doesn't have an output; its "output" is the state in which it leaves 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) : Unit {
        body (...) {
            // your code here
        }
        adjoint auto;
    }
}
