Problem 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).

Solution

/**
 * @param {number[]} nums
 * @return {number}
 */
var maxProduct = function(nums) {
  const [a, b] = nums.sort((a, b) => b - a);
  return (a - 1) * (b - 1);
};
