##### Canadian Computing Competition: 2017 Stage 1, Junior #5, Senior #3

Tudor is a contestant in the Canadian Carpentry Challenge (CCC). To win the CCC, Tudor must demonstrate his skill at nailing wood together to make the longest fence possible using boards. To accomplish this goal, he has pieces of wood. The piece of wood has integer length .

A *board* is made up of **exactly two** pieces of wood. The length of a board made of wood with lengths and is . A *fence* consists of boards that are the same length. The *length of the fence* is the number of boards used to make it, and the *height of the fence* is the length of each board in the fence. In the example fence below, the length of the fence is 4; the height of the fence is 50; and, the length of each piece of wood is shown:

Tudor would like to make the longest fence possible. Please help him determine the maximum length of any fence he could make, and the number of different heights a fence of that maximum length could have.

#### Input Specification

The first line will contain the integer .

The second line will contain space-separated integers .

For 5 of the 15 available marks, .

For an additional 4 of the 15 available marks, .

For an additional 3 of the 15 available marks, .

#### Output Specification

Output two integers on a single line separated by a single space: the length of the longest fence and the number of different heights a longest fence could have.

#### Sample Input 1

```
4
1 2 3 4
```

#### Sample Output 1

`2 1`

#### Explanation for Sample Output 1

Tudor first combines the pieces of wood with lengths and to form a board of length .

Then he combines the pieces of wood with lengths and to form another board of length .

Finally, he combines the boards to make a fence with length and height .

#### Sample Input 2

```
5
1 10 100 1000 2000
```

#### Sample Output 2

`1 10`

#### Explanation for Sample Output 2

Tudor can't make a fence longer than length , and there are ways to make a fence with length by choosing any two pieces of wood to nail together.

Specifically, he may have a fence of height , , , , , , , , and .

## Comments

I'm tryna check which test case my code fails on but I don't know which one it is cuz test data isn't properly numbered. Is there a way I can find out what subtask 1 test 2 is in the input files ?

Problem testcases are weighted out of 15.

I submitted the same code and there was a difference of 1s. Is there some new rule where there is a performance penalty for submitting more times?

why does this have so many downvotes?

There is no penalty for resubmitting. DMOJ uses multiple judges and you may have gotten different judges, which mark at varying speeds. The load on the judges also affects the speed, but if you're getting TLE (Time Limit Exceeded) and think your program is fine, just resubmit later. You can see the status of the judges at https://dmoj.ca/status/.
