Why do I get WA 1???
Posted by Bebop 22 Nov 2020 09:33
#include <iostream>
#include <string>
#include <vector>
#include <set>

const std::string &solution(const std::vector<std::string> &penguins);

int main() {
int n;
std::cin >> n;
std::cin.clear();
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
std::vector<std::string> penguins;
penguins.reserve(n);
for (int i = 0; i < n; ++i) {
std::string penguin;
std::getline(std::cin, penguin);
penguins.emplace_back(std::move(penguin));
}
std::cout << solution(penguins) << std::endl;
return 0;
}

const std::string &solution(const std::vector<std::string> &penguins) {
std::set<std::string> penguinSet(penguins.begin(), penguins.end());
auto setIterator = penguinSet.begin();
std::set<std::string>::iterator mostNumerous;
int maxCount = 0;
while (setIterator != penguinSet.end()) {
int count = 0;
for (const auto &penguin : penguins) {
if (*setIterator == penguin) {
count++;
}
}
if (count > maxCount) {
maxCount = count;
mostNumerous = setIterator;
}
setIterator++;
}
return *mostNumerous;
}

I tested locally and it works...
