#include <algorithm>
#include <iostream>
#include <bits/stdc++.h>
#include <vector>
using namespace std;
int main() {
int n;
cin >> n;
vector<int> data(n);
for(int i = 0; i < n; ++i) {
cin >> data[i];
}
int flag;
cin >> flag;
sort(begin(data), end(data));
if (flag == 0) {
for (int i = 0; i < n; ++i) {
cout << data[i];
if (i < n - 1) {
cout << " ";
} else {
cout << endl;
}
}
} else {
for (int i = n - 1; i >= 0; --i) {
cout << data[i];
if (i > 0) {
cout << " ";
} else {
cout << endl;
}
}
}
}
// 64 位输出请用 printf("%lld")
