C++实现输入整数排序去重输出

```cpp #include <iostream> #include <set> using namespace std; int main() { int n; cin >> n; set<int> numbers; for (int i = 0; i < n; i++) { int num; cin >> num; numbers.insert(num); } for (auto it = numbers.begin(); it != numbers.end(); ++it) { if (it != numbers.begin()) { cout << " "; } cout << *it; } cout << endl; return 0; } ``` ######[AI问答 | 156点数解答 | 2026-05-16 20:41:36]
