We need a function ```count_sel()``` that receives an array or list of integers (positive and negative) and may give us the following information in the order and  structure presented bellow:

```[(1), (2), (3), [[(4)], 5]]```

(1) - Total amount of received integers.

(2) - Total amount of different values the array has.

(3) - Total amount of values that occur only once.

(4) and (5) both in a list

(4) - It is (or they are) the element(s) that has (or have) the maximum occurrence. If there are more than one, the elements should be sorted (by their value obviously)

(5) - Maximum occurrence of the integer(s)

Let's see some cases
```python
____ count_sel([-3, -2, -1, 3, 4, -5, -5, 5, -1, -5]) ----> [10, 7, 5, [[-5], 3]]

(1) - The list has ten elements (10 numbers)

(2) - We have seven different values: -5, -3, -2, -1, 3, 4, 5 (7 values)

(3) - The numbers that occur only once: -3, -2, 3, 4, 5 (5 values)

(4) and (5) - The number -5 occurs three times (3 occurrences)

____ count_sel([4, 4, 2, -3, 1, 4, 3, 2, 0, -5, 2, -2, -2, -5]) ----> [14, 8, 4, [[2, 4], 3]]
```
Enjoy it and happy coding!!
