You are given an integer array nums.
Choose three elements a, b, and c from nums at distinct indices such that the value of the expression a + b - c is maximized.
Return an integer denoting the maximum possible value of this expression.
Example 1:
Input: nums = [1,4,2,5]
Output: 8
Explanation:
We can choose a = 4, b = 5, and c = 1. The expression value is 4 + 5 - 1 = 8, which is the maximum possible.
Example 2:
Input: nums = [-2,0,5,-2,4]
Output: 11
Explanation:
We can choose a = 5, b = 4, and c = -2. The expression value is 5 + 4 - (-2) = 11, which is the maximum possible.
Constraints:
3 <= nums.length <= 100-100 <= nums[i] <= 100
