You are playing one RPG from the 2010s. You are planning to raise your smithing skill, so you need as many resources as possible. So how to get resources? By stealing, of course.

You decided to rob a town's blacksmith and you take a follower with you. You can carry at most $p$ units and your follower — at most $f$ units.

In the blacksmith shop, you found $cnt_s$ swords and $cnt_w$ war axes. Each sword weights $s$ units and each war axe — $w$ units. You don't care what to take, since each of them will melt into one steel ingot.

What is the maximum number of weapons (both swords and war axes) you and your follower can carry out from the shop?

The first line contains a single integer $t$ ( $1 \le t \le 10^4$ ) — the number of test cases.

The first line of each test case contains two integers $p$ and $f$ ( $1 \le p, f \le 10^9$ ) — yours and your follower's capacities.

The second line of each test case contains two integers $cnt_s$ and $cnt_w$ ( $1 \le cnt_s, cnt_w \le 2 \cdot 10^5$ ) — the number of swords and war axes in the shop.

The third line of each test case contains two integers $s$ and $w$ ( $1 \le s, w \le 10^9$ ) — the weights of each sword and each war axe.

It's guaranteed that the total number of swords and the total number of war axes in all test cases don't exceed $2 \cdot 10^5$ .

For each test case, print the maximum number of weapons (both swords and war axes) you and your follower can carry.
