Naman owns a very famous Ice Cream parlour in Pune. He has a wide range of flavours with different pricing. 

Every flavour costs ₹ X per gram and quantity of each flavour in the parlour is indefinite. Now, Naman has 

received an order for a party wherein he is asked to prepare each Ice Cream with N number of flavours. 

He needs to prepare each Ice Cream of W grams and at the same time has to keep the cost minimum. 

Can you help him out?

Note: If it is not possible to prepare such an Ice Cream, print “Not Possible”.

-----Input:-----

First line contains an integer T denoting the number of test cases.

First line of every test case contains an integer N denoting the number of flavours.

The second line of every test case by N space separated integers denoting the cost per gram of each flavour. 

Second line of every test case contains two space separated integers W and Y denoting the weight 

of Ice Cream in grams and the number of flavours to be used respectively. 

-----Output:-----

For each test case, print the total cost of the Ice Cream in a single line.

-----Constraints:-----
1 ≤ T ≤ 100
1 ≤ N,W,Y ≤ 40000

-----Example:-----Input:

Not Possible

-----Explanation:-----

In the first test case to achieve the minimum cost, the Ice Cream will consist of 8 grams 

of flavour costing ₹1, 1 gram of flavour costing ₹4 and 1 gram of flavour costing ₹6.

In the second test case it is not possible to make an ice-cream weighing 1 gram using 2 flavours.
