# 1464. Maximum Product of Two Elements in an Array

<https://leetcode.com/problems/maximum-product-of-two-elements-in-an-array>

## Description

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`
