Node* reverseLinkedList(Node* head) {
    Node* prev = nullptr;
    Node* current = head;
    Node* next = nullptr;

    while (current != nullptr) {
        next = current->next;  // Store the next node
        current->next = prev;  // Reverse the link

        // Move pointers one position ahead
        prev = current;
        current = next;
    }

    // Return the new head of the reversed list
    return prev;
}
