How can I find and remove duplicate vectors in C++?

How can I find and remove duplicate vectors in C++?

You can use the std::set to store unique vectors or use std::unique with std::vector to remove duplicates.

Can you show me a code example for that?

Sure! Here's a simple example:

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> vec = {1, 2, 2, 3, 4, 4, 5};
    std::sort(vec.begin(), vec.end());
    auto last = std::unique(vec.begin(), vec.end());
    vec.erase(last, vec.end());
    for (int n : vec) std::cout << n << ' ';
    return 0;
}

What if I have a vector of custom objects?

You can define a custom comparator for your objects and use std::set or std::unique with that comparator.
