Mas在学习分式。a1+1/a2+1/a3+1/a4+1/... 他需要求出这个连分数的值,给出a[]的具体值,请你输出最终的结果(保留两位小数) 输入格式 第一行输出一个正整数n 第二行n个正整数,表示a1∼an 输出格式 一个数,保留2位小数。C++

在C++中,计算无限连分数可以采用迭代的方式来逐步逼近其实际值。由于题目提到的是有限长度序列,我们可以编写一个函数来处理这个问题。以下是一个简单的C++程序示例:
```cpp
#include <iostream>
#include <vector>
using namespace std;
double calculateContinuedFraction(vector<int>& a) {
double result = a[0]; // 初始化结果为第一个分数a1
for (size_t i = 1; i < a.size(); ++i) {
result += 1.0 / (a[i]);
}
return round(result * 100.0) / 100.0; // 四舍五入并保留两位小数
}
int main() {
int n;
cin >> n;
vector<int> a(n);
for (int i = 0; i < n; ++i) {
cin >> a[i];
}
double value = calculateContinuedFraction(a);
cout << fixed << setprecision(2) << value << endl;

There could be a few reasons why you are unable to access the GitHub repository at the URL you provided. One possible reason is that the repository owner has restricted access to certain users or is no longer available. Another reason could be that your IP address has been blocked by GitHub, either because of suspicious activity or violation of their terms of service.
If you are the owner of the repository, you can check your permissions settings to ensure that the repository is set to public or that you have granted access to any users who are having trouble accessing it. If you are not the owner, you may need to contact the owner or GitHub support for further assistance. Additionally, you could try accessing the repository from a different network or device to see if the issue is related to your current setup.
