一、题目
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
二、题解
class Solution {
public:int integerBreak(int n) {vector<int>dp(n+1,0);dp[2] = 1;for(int i = 3;i <= n;i++){for(int j = 1;j < i;j++){dp[i] = max(dp[i],max(j * dp[i-j],j * (i-j)));}}return dp[n];}
};
