# Find the Highest Altitude Lab

In this lab, you will be working on a problem involving a biker going on a road trip. The road trip consists of `n + 1`

points at different altitudes. The biker starts his trip on point `0`

with an altitude equal to `0`

.

You are given an integer array `gain`

of length `n`

where `gain[i]`

is the **net gain in altitude** between points `i`

and `i + 1`

for all (`0 <= i < n`

). Your task is to return the **highest altitude** of a point.

## Examples

Consider the following examples:

**Example 1:**

**Input:** gain = [-5, 1, 5, 0, -7]
**Output:** 1
**Explanation:** The altitudes are [0, -5, -4, 1, 1, -6]. The highest is 1.

**Example 2:**

**Input:** gain = [-4, -3, -2, -1, 4, 3, 2]
**Output:** 0
**Explanation:** The altitudes are [0, -4, -7, -9, -10, -6, -3, -1]. The highest is 0.

## Constraints

While working on this problem, keep the following constraints in mind:

`n == gain.length`

`1 <= n <= 100`

`-100 <= gain[i] <= 100`

## Requirements

To complete this lab, you need to implement the `largestAltitude`

function and export it, so it can be properly tested by the provided evaluation script. Make sure to export the function as specified in the challenges:

`/** * @param {number[]} gain * @return {number} */ export const largestAltitude = function(gain) { };`

## Challenges

- Export the
`largestAltitude`

function from your main file. - Implement the
`largestAltitude`

function in your main file that takes the`gain`

integer array and returns the highest altitude.

Good luck, and have fun working on this lab!
