7179：BIT Subway

BIT(Beijing International Transport) subway, which can take people anywhere in a short time, is the most popular travel mode in 2050. One day, BIT subway launches a promotion as follows:

- If the total ticket price $x$ you have spent this month is greater than or equal to 100 and you buy another ticket with ￥$y$, then you only need to pay ￥$0.8y$.
- If the total ticket price $x$ you have spent this month is greater than or equal to 200 and you buy another ticket with ￥$y$, then you only need to pay ￥$0.5y$.

DLee is so happy that he can save more money to buy a house. However, a long time later, he notices that the real billing method is a bit different from what he thought. For example, DLee has spent ￥199 on tickets this month, he now buys a ￥10 ticket, then buys an ￥8 ticket:

- DLee thinks that he can buy only a part of the ticket instead of the whole ticket at a time. That is, for the ￥10 ticket, DLee thinks he can buy the ￥1.25 part of the ticket first and buy the ￥8.75 part of the ticket then. Under his misunderstanding, he needs to spend $199+1.25\*0.8+8.75\*0.5+8\*0.5=$￥$208.375$. Note that in this example, DLee has to spend ￥1.25 instead of only ￥1 to make $x=200$.
- The real billing method is that only if you have spent enough, you can get the discount, so it will be $199+10\*0.8+8\*0.5=￥211$.

Now DLee wants to know in the previous months, how much difference did the billing method make.

Each test contains multiple test cases. The first line contains one integer $T(1\leq T\leq 10)$, which means the months DLee wants to check. Description of the months follows.

The first line contains a single integer $n(1\leq n \leq 10^5)$, which means the number of tickets DLee bought in this month.

Then follows $n$ integers $a_1,a_2,\ldots,a_n(1 \leq a_i \leq 200)$, $a_i$ means the $i$-th ticket's price.

For each month, output one line with two numbers divided by a single whitespace with three decimal places. The first number represents the cost in DLee's thought, and the second number represents the real cost.
