C++实现非负整数排序去重

```cpp #include <iostream> #include <set> int main() { int n; std::cin >> n; std::set<int> numbers; for (int i = 0; i < n; ++i) { int num; std::cin >> num; numbers.insert(num); } for (auto it = numbers.begin(); it != numbers.end(); ++it) { if (it != numbers.begin()) { std::cout << " "; } std::cout << *it; } std::cout << std::endl; return 0; } ``` ######[AI问答 | 166点数解答 | 2026-02-26 14:14:33]
