See the following triangle:
```
____________________________________
 1                                      
 2   4   2                              
 3   6   9   6   3                      
 4   8   12  16  12  8   4             
 5   10  15  20  25  20  15  10  5   
 ___________________________________
```
The total sum of the numbers in the triangle, up to the 5th line included, is ```225```, part of it, ```144```, corresponds to the total sum of the even terms and ```81``` to the total sum of the odd terms.
Create a function that may output an array with three results for each value of n.
```python
triang_mult(n)  ----> [total_sum, total_even_sum, total_odd_sum]
```
Our example will be:
```python
triang_mult(5) ----> [225, 144, 81]
```
Features of the random tests:
```
number of tests = 100
49 < n < 5000
```
Enjoy it!
