# Solving Leetcode Interviews in Seconds with AI: Find the Highest Altitude


	# Introduction
	In this blog post, we will explore how to solve the LeetCode problem "1732" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like [Chatmagic](https://www.chatmagic.app), we can generate solutions quickly and efficiently - helping you pass the interviews and get the job offer without having to study for months.

	# Problem Statement
	> 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: 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:  n == gain.length 1 <= n <= 100 -100 <= gain[i] <= 100  

	# Explanation
	*   **Keep Track of Current Altitude:** Iterate through the `gain` array, maintaining a running sum that represents the current altitude.
*   **Track Maximum Altitude:** Simultaneously, keep track of the highest altitude encountered so far.
*   **Update Max Altitude:** In each iteration, update the maximum altitude if the current altitude is higher.

*   **Runtime Complexity:** O(n), where n is the length of the `gain` array. **Storage Complexity:** O(1).

	
	# Code
	```python
	def largestAltitude(gain: list[int]) -> int:
    """
    Calculates the highest altitude reached during a biking trip.

    Args:
        gain: A list of integers representing the net gain in altitude between points.

    Returns:
        The highest altitude reached during the trip.
    """

    max_altitude = 0
    current_altitude = 0

    for altitude_gain in gain:
        current_altitude += altitude_gain
        max_altitude = max(max_altitude, current_altitude)

    return max_altitude
