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
