Answer 1

#include <iostream>

#include <vector>

std::vector<std::string> getUniqueBrands(const std::vector<std::string>& brand1, const std::vector<std::string>& brand2)

{

std::vector<std::string>res;

for(auto element : brand2)

{

if(element!="PRADA")

res.push_back(element);

}

for(auto element : brand1)

{

if(element!="HERMES")

res.push_back(element);

}

return res;

}

int main()

{

std::vector<std::string> brand1 = {"LOUIS_VUITTON", "HERMES", "PRADA"};

std::vector<std::string> brand2 = {"GUCCI", "PRADA", "HERMES"};

std::vector<std::string> result = getUniqueBrands(brand1, brand2);

for(auto element : result)

{

std::cout << element << ' '; // should print GUCCI HERMES LOUIS_VUITTON PRADA

}
