Given an integer n, break it into the sum of k positive integers, where k >= 2, and maximize the product of those integers.
Return the maximum product you can get.
Example 1:
Input: n = 2 Output: 1 Explanation: 2 = 1 + 1, 1 × 1 = 1.
Example 2:
Input: n = 10 Output: 36 Explanation: 10 = 3 + 3 + 4, 3 × 3 × 4 = 36.
Constraints:
2 <= n <= 58
