阿弥诺斯的代码有两种，分开写；
// 记忆化搜索
#include <iostream>
#include <vector>
using namespace std;
vector <int> memo(501,-1);
int countSequences(int n){
if(n == 1) return 1;
if(memo[n] != -1) return memo[n];
int result = 1;
for(int i = 1;i <= n / 2;++i){
result += countSequences(i);
}
memo[n] = result;
return result;
}
int main(){
int n;
cin >> n;
cout << countSequences(n) << endl;
return 0;
}
//动态规划
// #include <iostream>
// #include <vector>
// using namespace std;
// int countSequences(int n){
// vector<int> dp(n + 1,0);
// dp[1] = 1;
// for(int i = 2;i <= n;i++){
// dp[i] = 1;
// for(int j = 1;j <= i / 2;++j){
// dp[i] += dp[j];
// }
// }
// return dp[n];
// }
// int main(){
// int n;
// cin >> n;
// cout << countSequences(n) << endl;
// return 0;
// }
