1464. Maximum Product of Two Elements in an Array¶
Given the array of integers nums, you will choose two different indices i
and j of that array. Return the maximum value of (nums[i]-1)*(nums[j]-1).
Example 1¶
Input: nums = [3,4,5,2]
Output: 12
Explanation: If you choose the indices i=1 and j=2 (indexed from 0), you will get the maximum value, that is, (nums[1]-1)*(nums[2]-1) = (4-1)*(5-1) = 3*4 = 12.
Example 2¶
Input: nums = [1,5,4,5]
Output: 16
Explanation: Choosing the indices i=1 and j=3 (indexed from 0), you will get the maximum value of (5-1)*(5-1) = 16.
Example 3¶
Constraints¶
2 <= nums.length <= 5001 <= nums[i] <= 10^3
