There Are Two Types Of Burgers
Description
There are two types of burgers in your restaurant — hamburgers and chicken burgers! To assemble a hamburger you need two buns and a beef patty. To assemble a chicken burger you need two buns and a chicken cutlet.
You have $b$ buns, $p$ beef patties and $f$ chicken cutlets in your restaurant. You can sell one hamburger for $h$ dollars and one chicken burger for $c$ dollars. Calculate the maximum profit you can achieve.
You have to answer $t$ independent queries.
The first line contains one integer $t$ ($1 \le t \le 100$) – the number of queries.
The first line of each query contains three integers $b$, $p$ and $f$ ($1 \le b, ~p, ~f \le 100$) — the number of buns, beef patties and chicken cutlets in your restaurant.
The second line of each query contains two integers $h$ and $c$ ($1 \le h, ~c \le 100$) — the hamburger and chicken burger prices in your restaurant.
For each query print one integer — the maximum profit you can achieve.

Note
In first query you have to sell two hamburgers and three chicken burgers. Your income is $2 \cdot 5 + 3 \cdot 10 = 40$.
In second query you have to ell one hamburgers and two chicken burgers. Your income is $1 \cdot 10 + 2 \cdot 12 = 34$.
In third query you can not create any type of burgers because because you have only one bun. So your income is zero.
