## 343. 整数拆分
|

|
||||
题目链接:https://leetcode-cn.com/problems/integer-break/
|
||||

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。

|
||||
|

j是从1开始遍历,拆分j的情况,在遍历j的过程中其实都计算过了。
|
||||
|
||||
那么从1遍历j,比较(i - j) * j和dp[i - j] * j 取最大的。
|
||||
**那有同学问了,j怎么就不拆分呢?**
|
||||
|
||||
j是从1开始遍历,拆分j的情况,在遍历j的过程中其实都计算过了。那么从1遍历j,比较(i - j) * j和dp[i - j] * j 取最大的。递推公式:dp[i] = max(dp[i], max((i - j) * j, dp[i - j] * j));
|
||||
|
||||
也可以这么理解,j * (i - j) 是单纯的把整数拆分为两个数相乘,而j * dp[i - j]是拆分成两个以及两个以上的个数相乘。
|
||||
|
||||
如果定义dp[i - j] * dp[j] 也是默认将一个数强制拆成4份以及4份以上了。
|
||||
|
||||
所以递推公式:dp[i] = max({dp[i], (i - j) * j, dp[i - j] * j});

递推公式:dp[i] = max(dp[i], max((i - j) * j, dp[i - j] * j));

直接使用set 不仅占用空间比数组大,而且速度要比数组慢,set把数值映射到key上都要做hash计算的。
