请不要把AC代码发出来，我正在练习骗分

第一个点为什么拿不到分？第一个点与第五个点错误

#include <bits/stdc++.h>
using namespace std;

long long n,a,b,c;

int main()
{
    cin >> n;
    for(int i = 1;i <= n;i++)
    {
        if(n == 3) cin >> a >> b >> c;
        else if(n == 2) cin >> a >> b;
        else if(n == 1) cin >> a;
    }
    if(n == 1)
    {
        cout << "0" << endl;
        return 0;
    }
    else if(n == 2)
    {
        cout << "1" << endl;
        return 0;
    }
    else if(n == 3)
    {
