## Description

https://leetcode.com/problems/find-the-highest-altitude/

There is 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 altitude equal `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)`

. Return *the highest altitude of a point.*

**Example 1:**

Input:gain = [-5,1,5,0,-7]Output:1Explanation: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:0Explanation:The altitudes are [0,-4,-7,-9,-10,-6,-3,-1]. The highest is 0.

**Constraints:**

`n == gain.length`

`1 <= n <= 100`

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

## Explanation

altitude = previous altitude + gain.

## Python Solution

```
class Solution:
def largestAltitude(self, gain: List[int]) -> int:
altitudes = []
altitudes.append(0)
for g in gain:
altitudes.append(g + altitudes[-1])
return max(altitudes)
```
