题解 | 输入n个整数，输出其中最小的k个

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;


int main() {
    int n, k;

    while (cin >> n >> k) {
        vector<int> arr = vector<int>(n, 0);

        for (int i = 0; i < n; i++)
            cin >> arr[i];

        sort(arr.begin(), arr.end());

        for (int i = 0; i < k; i++)
            cout << arr[i] << " ";

        cout << endl;
    }


    return 0;
}
