C++ 编程：构造满足特定条件的序列

#include #include using namespace std;

int main() { int x; cin >> x;

while (x--) {
    int n;
    cin >> n;
    
    vector<int> a(n);
    for (int i = 0; i < n; i++) {
        a[i] = i + 1;
    }
    
    int sum = 0;
    for (int i = 0; i < n; i++) {
        sum += a[i];
    }
    
    int k = sum / n;
    
    for (int i = 0; i < n; i++) {
        a[i] *= k;
    }
    
    for (int i = 0; i < n; i++) {
        cout << a[i] << " ";
    }
    cout << endl;
}

return 0;
