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`
