# Maximum Average Subarray I

In this lab, you will work on an algorithm that finds the contiguous subarray of a given length `k`

with the maximum average value. This is an important and useful problem in many daily life scenarios related to finance, data analysis, etc.

You will be given an integer array `nums`

consisting of `n`

elements and an integer `k`

. Your task is to find a contiguous subarray whose **length is equal to** `k`

that has the maximum average value, and return this value. Any answer with a calculation error less than `10-5`

will be accepted.

For example:

**Input:** nums = [1,12,-5,-6,50,3], k = 4
**Output:** 12.75000
**Explanation:** Maximum average is (12 - 5 - 6 + 50) / 4 = 51 / 4 = 12.75

**Input:** nums = [4,2,1,3,4], k = 2
**Output:** 3.50000
**Explanation:** Maximum average is (3 + 4) / 2 = 3.5

In this lab, you will write a function named `findMaxAverage`

that takes two parameters:

`nums`

: An integer array consisting of`n`

elements.`k`

: The length of the subarray to be found.

Function signature:

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

Make sure to properly import and export the `findMaxAverage`

function so it can be tested in the evaluation script.

## Challenges

- Implement the
`findMaxAverage`

function and make sure it returns the maximum average for a given subarray of length`k`

. - Test the function with multiple test cases to ensure its correctness, and handle edge cases if necessary.
- Export the
`findMaxAverage`

function properly, so it can be imported in the evaluation script.

Now, complete the lab by writing the evaluation script, making sure it properly tests your implementation and properly logs the test results. Also, make sure to follow the rules we discussed earlier for building this lab. Good luck!
