LeetCode 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:

Input: nums = [3,7]
Output: 12


2 <= nums.length <= 500
1 <= nums[i] <= 10^3

int maxProduct(int* nums, int numsSize){
    int m1=0, m2=0;
    for(int i=0;i<numsSize;++i){
        else if(nums[i]>m2){
    return (m1-1)*(m2-1);
