为什么WA了

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main() {
    int n;
    cin >> n;
    vector<int> nums(n);
    for (int i = 0; i < n; i++) {
        cin >> nums[i];
    }
    sort(nums.rbegin(), nums.rend());
    vector<int> team1, team2;
    for (int num : nums) {
        if (team1.size() <= team2.size()) {
            team1.push_back(num);
        } else {
            team2.push_back(num);
        }
    }
    cout << team1.size() << endl;
    for (int num : team1) {
        cout << num << " ";
    }
    cout << endl;
    cout << team2.size() << endl;
    for (int num : team2) {
        cout << num << " ";
    }
    cout << endl;
    return 0;
