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

``````public class Solution {
public int LargestAltitude(int[] gain) {
int max = 0;
int altitude=0;
for(int i=0;i<gain.Length;i++){
altitude += gain[i];
max = Math.Max(max,altitude);
}

return max;
}
}``````

Time Complexity: O(n)

Space Complexity: O(1)
