```cpp #include <iostream> #include <set> using namespace std; int main() { int n; cin >> n; set<int> nums; for (int i = 0; i < n; i++) { int num; cin >> num; nums.insert(num); } for (auto it = nums.begin(); it != nums.end(); ++it) { if (it != nums.begin()) { cout << " "; } cout << *it; } cout << endl; return 0; } ``` ######[AI问答 | 158点数解答 | 2026-02-25 22:39:47]
