# Sort Even and Odd Indices Independently

In this lab, you will be working on a function that takes an array of integers and sorts it in a way that values present at **odd indices** are sorted in **non-increasing** order, and values present at **even indices** are sorted in **non-decreasing** order. You will be using ESM import/export syntax throughout the lab.

**Function signature:**

`/** * @param {number[]} nums * @return {number[]} */ var sortEvenOdd = function(nums) { };`

## Description

Given a **0-indexed** integer array `nums`

, you need to rearrange the values of `nums`

according to the following rules:

- Sort the values at
**odd indices**of`nums`

in**non-increasing**order.- For example, if
`nums = [4,1,2,3]`

before this step, it becomes`[4,3,2,1]`

after. The values at odd indices`1`

and`3`

are sorted in non-increasing order.

- For example, if
- Sort the values at
**even indices**of`nums`

in**non-decreasing**order.- For example, if
`nums = [4,1,2,3]`

before this step, it becomes`[2,1,4,3]`

after. The values at even indices`0`

and`2`

are sorted in non-decreasing order.

- For example, if

Return *the array formed after rearranging the values of* `nums`

.

## Examples

**Example 1:**

**Input:** nums = [4,1,2,3]
**Output:** [2,3,4,1]
**Explanation:**
First, we sort the values present at odd indices (1 and 3) in non-increasing order.
So, nums changes from [4,**1**,2,**3**] to [4,**3**,2,**1**].
Next, we sort the values present at even indices (0 and 2) in non-decreasing order.
So, nums changes from [**4**,1,**2**,3] to [**2**,3,**4**,1].
Thus, the array formed after rearranging the values is [2,3,4,1].

**Example 2:**

**Input:** nums = [2,1]
**Output:** [2,1]
**Explanation:**
Since there is exactly one odd index and one even index, no rearrangement of values takes place.
The resultant array formed is [2,1], which is the same as the initial array.

**Constraints:**

`1 <= nums.length <= 100`

`1 <= nums[i] <= 100`

In order to successfully pass this lab, make sure you export the `sortEvenOdd`

function properly, as it will be used in the evaluation script to test your code.
