    Problem

    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:

    Solution

    /**
     * @param {number[]} gain
     * @return {number}
     */
    var largestAltitude = function(gain) {
        var max = 0;
        var cur = 0;
        for (var i = 0; i < gain.length; i++) {
            cur += gain[i];
            max = Math.max(max, cur);
        }
        return max;
    };
    

    Explain:

    nope.
