What are some advanced data structures in C++?

Some advanced data structures in C++ include trees, graphs, hash tables, and heaps. Would you like to know more about any specific one?

Can you explain how a binary tree works?

A binary tree is a hierarchical structure where each node has at most two children, referred to as the left and right child. It's used for various applications like searching and sorting.

What is the difference between a binary tree and a binary search tree?

A binary tree is a general tree structure, while a binary search tree (BST) is a specific type of binary tree where the left child is less than the parent and the right child is greater, allowing for efficient searching.

How do I implement a graph in C++?

You can implement a graph in C++ using an adjacency list or an adjacency matrix. Would you like a code example for one of these methods?

Yes, please provide an example of an adjacency list implementation.

Sure! Here's a simple implementation of a graph using an adjacency list in C++:

#include <iostream>
#include <vector>
using namespace std;

class Graph {
    int V; // Number of vertices
    vector<vector<int>> adj; // Adjacency list
public:
    Graph(int V) : V(V) {
        adj.resize(V);
    }
    void addEdge(int u, int v) {
        adj[u].push_back(v);
        adj[v].push_back(u); // For undirected graph
    }
    void printGraph() {
        for (int i = 0; i < V; i++) {
            cout << "Vertex " << i << " : ";
            for (int j : adj[i]) {
                cout << j << " ";
            }
            cout << endl;
        }
    }
};

int main() {
    Graph g(5);
    g.addEdge(0, 1);
    g.addEdge(0, 4);
    g.addEdge(1, 2);
    g.addEdge(1, 3);
    g.addEdge(1, 4);
    g.addEdge(2, 3);
    g.addEdge(3, 4);
    g.printGraph();
    return 0;
}

This code creates a graph with 5 vertices and adds some edges.
