#P1002A1. Generate superposition of all basis states
Generate superposition of all basis states
Description
You are given N qubits (1 ≤ N ≤ 8) in zero state 
. 
Your task is to generate an equal superposition of all 2N basis vectors on N qubits:

For example,
-  for N = 1, the required state is simply 
, -  for N = 2, the required state is 
.  
You have to implement an operation which takes an array of N qubits as an input and has no output. The "output" of the operation 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 (qs : Qubit[]) : ()
    {
        body
        {
            // your code here
        }
    }
}
