1464 - Maximum Product of Two Elements in an Array\.
Easy
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:**
**Input:** nums = [3,7]
**Output:** 12
**Constraints:**
* `2 <= nums.length <= 500`
* `1 <= nums[i] <= 10^3`
