Given a positive integer n, break it into the sum of at least two positive integers and maximize the product of those integers. Return the maximum product you can get. For example, given n = 2, return 1 (2 = 1 + 1); given n = 10, return 36 (10 = 3 +…

Given a positive integer n, break it into the sum of at least two positive integers and maximize the product of those integers. Return the maximum product you can get. Example 1: Input: 2 Output: 1 Explanation: 2 = 1 + 1, 1 × 1 = 1. Example 2: Input:…

给定一个正整数 n,将其拆分为至少两个正整数的和,并使这些整数的乘积最大化. 返回你可以获得的最大乘积.例如,给定 n = 2,返回1(2 = 1 + 1):给定 n = 10,返回36(10 = 3 + 3 + 4).注意:你可以假设 n 不小于2且不大于58. 详见:https://leetcode.com/problems/integer-break/description/ C++: class Solution { public: int integerBreak(int n) { i…
