**Objective**

In this challenge, we practice using *arrow functions*. Check the attached tutorial for more details.

**Task**

Complete the function in the editor. It has one parameter: an array, . It must iterate through the array performing one of the following actions on each element:

- If the element is even, multiply the element by .
- If the element is odd, multiply the element by .

The function must then return the modified array.

**Input Format**

The first line contains an integer, , denoting the size of .

The second line contains space-separated integers describing the respective elements of .

**Constraints**

- , where is the element of .

**Output Format**

Return the modified array where every even element is doubled and every odd element is tripled.

**Sample Input 0**

```
5
1 2 3 4 5
```

**Sample Output 0**

```
3 4 9 8 15
```

**Explanation 0**

Given , we modify each element so that all even elements are multiplied by and all odd elements are multipled by . In other words, . We then return the modified array as our answer.
