The problem

You are given a 0-indexed integer array nums. Return the maximum value over all triplets of indices (i, j, k) such that i < j < k.

Example

Input
nums = [12,6,1,2,7]
Output
77
Explanation
The value of the triplet (0, 2, 4) is (nums[0] - nums[2]) * nums[4] = 77.

Python solution

Python
class Solution:
    def maximumTripletValue(self, nums: List[int]) -> int:
        ans = mx = mx_diff = 0
        for x in nums:
            ans = max(ans, mx_diff * x)
            mx_diff = max(mx_diff, mx - x)
            mx = max(mx, x)
        return ans
