C ++中的整数中断
让我们看下面的实现以更好地理解-
#include <bits/stdc++.h>
using namespace std;
class Solution {
public:
int solve(int n, vector <int>& dp, bool flag = true){
if(n == 0) return 1;
if(dp[n] != -1) return dp[n];
int end = flag? n - 1: n;
int ret = 0;
for(int i = 1; i <= end; i++){
ret = max(ret, i * solve(n - i, dp, false));
}
return dp[n] = ret;
}
int integerBreak(int n) {
vector <int>dp(n + 1, -1);
return solve(n, dp);
}
};
main(){
Solution ob;
cout << (ob.integerBreak(10));
}输入值
10
输出结果
36
