#include <iostream>
#include <vector>
int main() {
std::vector<int> list = {1, 2, 3, 3, 4, 4, 5};
std::vector<int> uniqueList;
for (int i = 0; i < list.size(); i++) {
bool isDuplicate = false;
for (int j = 0; j < i; j++) {
if (list[i] == list[j]) {
isDuplicate = true;
break;
}
}
if (!isDuplicate) {
uniqueList.push_back(list[i]);
}
}
for (int i = 0; i < uniqueList.size(); i++) {
std::cout << uniqueList[i] << " ";
}
return 0;
}
