How do I implement an advanced hash table in C++?

To implement an advanced hash table in C++, you can use the STL's unordered_map or create your own class. Would you like to see an example?

Yes, please show me an example of a custom hash table.

Here's a simple implementation:

#include <iostream>
#include <list>
#include <vector>

class HashTable {
private:
    static const int hashSize = 10;
    std::list<std::pair<int, std::string>> table[hashSize];

public:
    void insert(int key, std::string value) {
        int index = key % hashSize;
        table[index].emplace_back(key, value);
    }

    std::string search(int key) {
        int index = key % hashSize;
        for (auto& pair : table[index]) {
            if (pair.first == key) {
                return pair.second;
            }
        }
        return "Not found";
    }
};

Would you like to know more about collision handling?

Yes, how do I handle collisions in this hash table?

In this implementation, collisions are handled using chaining, where each index in the hash table points to a list of entries. When a collision occurs, you simply add the new entry to the list at that index. Would you like to explore other collision resolution techniques?
