## Introduction to Data Structure through C++

An information structure is a gathering of information components assembled under one name. These information components, known as individuals, can have various sorts and various lengths.

C/C++ exhibits permit you to characterize factors that consolidate a few information things of a similar kind, however structure is another client characterized information type which permits you to join information things of various types.

Structures are utilized to speak to a record, assume you need to monitor your books in a library. You should follow the accompanying ascribes about each book −

- Title
- Creator
- Subject
- Book ID

### Data Structure through C++ Curriculum

The best way to make your preparation effective is with an initial idea and an outline of the Data Structure through C++ Syllabus. Keeping in mind every student’s requirements, we have provided a detailed view of the Data Structure through C++ curriculum.

Data Structure through C++ Course Curriculum will give students a clear idea of what to study, and the unit-wise break up gives topics under each unit carefully and allot time to each topic.

Students must cover all the topics before attempting the Data Structure through C++ exam so that the paper is reasonably comfortable at the time of the exam. Candidates must ensure awareness of the Data Structure through C++ Syllabus as it prevents you from wasting unnecessary time on redundant topics.

The updated unit-wise breakup of the Data Structure through C++ Syllabus is as follows-

### List of Data Structure through C++ Important Questions

Candidates studying Data Structure through C++ can go through the list of essential questions mentioned below for the Data Structure through C++ course programme. All the given review questions aim to help the candidates to excel in the examination.

- What are linear and nonlinear data Structures?
- What are the various operations that can be performed on different Data Structures?
- How is an Array different from Linked List?
- What is Stack and where it can be used?
- What is a Queue, how it is different from stack and how is it implemented?
- What are Infix, prefix, Postfix notations?
- What is a Linked List and What are its types?
- Which data structures are used for BFS and DFS of a graph?
- Can doubly linked be implemented using a single pointer variable in every node?
- How to implement a stack using a queue?

### Frequently Asked Questions on Data Structure through C++ Notes

**Question 1.**

How to implement a queue using stack?

**Answer:**

A queue can be implemented using two stacks. Let queue to be implemented be q and stacks used to implement q be stack1 and stack2. q can be implemented in two ways:

- Method 1 (By making enQueue operation costly)
- Method 2 (By making deQueue operation costly)

**Question 2.**

Which Data Structure Should be used for implementing LRU cache?

**Answer:**

We use two data structures to implement an LRU Cache.

- Queue which is implemented using a doubly linked list. The maximum size of the queue will be equal to the total number of frames available (cache size).
- The most recently used pages will be near the rear end and least recently pages will be near the front end.
- A Hash with page number as key and address of the corresponding queue node as value.

**Question 3. **

How to check if a given Binary Tree is BST or not?

**Answer:**

If in order traversal of a binary tree is sorted, then the binary tree is BST. The idea is to simply do in order traversal and while traversing keep track of previous key value. If the current key value is greater, then continue, else return false.
