Problem Description
The Task:
Your mission is to write C++ code to implement a simple binary search tree. The tree should support operations such as insertion, deletion, and searching for a value.
How to Approach the Problem:
Let's break down the problem into manageable steps:
Step 1: Node Class
Create a C++ class named Node to represent a node in the binary search tree. Each node should contain a data field, a pointer to the left child, and a pointer to the right child.
#include <iostream>
class Node {
public:
int data;
Node* left;
Node* right;
Node(int value) : data(value), left(nullptr), right(nullptr) {}
};
Step 2: BinarySearchTree Class
Create another C++ class named BinarySearchTree to represent the binary search tree. Define methods for inserting a node, deleting a node, and searching for a value.
#include <iostream>
class Node {
public:
int data;
Node* left;
Node* right;
Node(int value) : data(value), left(nullptr), right(nullptr) {}
};
class BinarySearchTree {
private:
Node* root;
Node* insert(Node* root, int value) {
if (root == nullptr) {
return new Node(value);
}
if (value < root->data) {
root->left = insert(root->left, value);
} else if (value > root->data) {
root->right = insert(root->right, value);
}
return root;
}
Node* remove(Node* root, int value) {
if (root == nullptr) {
return nullptr;
}
if (value < root->data) {
root->left = remove(root->left, value);
} else if (value > root->data) {
root->right = remove(root->right, value);
} else {
if (root->left == nullptr) {
Node* temp = root->right;
delete root;
return temp;
} else if (root->right == nullptr) {
Node* temp = root->left;
delete root;
return temp;
}
Node* successor = findMin(root->right);
root->data = successor->data;
root->right = remove(root->right, successor->data);
}
return root;
}
bool search(Node* root, int value) const {
if (root == nullptr) {
return false;
}
if (value == root->data) {
return true;
} else if (value < root->data) {
return search(root->left, value);
} else {
return search(root->right, value);
}
}
Node* findMin(Node* root) const {
while (root->left != nullptr) {
root = root->left;
}
return root;
}
public:
BinarySearchTree() : root(nullptr) {}
void insert(int value) {
root = insert(root, value);
}
void remove(int value) {
root = remove(root, value);
}
bool search(int value) const {
return search(root, value);
}
};
Step 3: Testing
Test your binary search tree implementation with different scenarios, ensuring it handles various insertions, deletions, and searches correctly.
Example
Let's walk through a sample scenario to solidify your understanding. The provided C++ solution serves as a guide to help you implement your own solution. Understand the logic behind each step and adapt it to your programming style.
#include <iostream>
int main() {
BinarySearchTree bst;
// Test binary search tree operations here
bst.insert(5);
bst.insert(3);
bst.insert(7);
std::cout << "Does 3 exist in the tree? " << (bst.search(3) ? "Yes" : "No") << std::endl; // Should print Yes
bst.remove(3);
std::cout << "Does 3 exist in the tree? " << (bst.search(3) ? "Yes" : "No") << std::endl; // Should print No
return 0;
}
This programming assignment offers a practical application of C++ programming by creating a binary search tree. As you progress through each step, you'll not only refine your coding skills but also gain a practical understanding of how binary search trees work and their applications.
