|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [3,4,5,2]
|
|
<strong>Output:</strong> 12
|
|
<strong>Explanation:</strong> 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.

|
|
<strong>Explanation:</strong> Choosing the indices i=1 and j=3 (indexed from 0), you will get the maximum value of (5-1)*(5-1) = 16.
