What is the time complexity of the following code?
Step by step
Solved in 2 steps
- in java : you need to start implementing a class for creating and storing Binary SearchTrees (BST). Each node of this BST will store the roll number, name and CGPA of a student.The class definitions will look like:class StudentBST;class StudentNode {friend class StudentBST;private:int rollNo;string name;Student’s CGPAStudentNode* left; // Pointer to the left subtree of a nodeStudentNode* right; // Pointer to the right subtree of a node};class StudentBST {private:StudentNode* root; // Pointer to the root node of the treepublic:StudentBST(); // Default constructor}; Write a menu-based driver function to illustrate the working of different functions of theStudentBST class. The menu should look like:1. Insert a new student2. Search for a student3. See the list of students4.
