Data Structures and Algorithm

Data Structures and Algorithm

A data structure is a specific location that we can use to store and organize the data, while an algorithm is a step-by-step guide to solve a problem. We can write efficient and optimized computer programs with the help of data structures and algorithm. Data structures and algorithm is one of the most important topics for placement and interview preparation. Here is a complete roadmap to cover all the data structure algorithm topics. It makes you comfortable with the most important algorithms in the data structure for your interviews.

Frequently Asked Questions

What is data structures and algorithm used for?

Data structures are used to store data, whereas algorithms are used to solve problems with that data.

What are various data structures available?

Some of the most common data structures are: Arrays, Stacks, Queues, Linked Lists, Graphs and Trees (Binary Tree, Binary Search Tree, AVL Tree, Red Black Tree, B+ Tree, B- Tree).

down-arrow

What are the 2 main types of data structures?

Two main types of data structures are Linear and Non-linear Data Structures. In the former, the elements are arranged one after the other while in non-linear data structure, the elements are arranged in a hierarchical manner. One element can be related to one or more elements.

How are data structures stored in memory?

Different data structures are stored differently in the memory. Like- All the elements of an array are stored in the continuous piece of memory, while the elements of a linked list can be stored at different places.

How many algorithms are there in data structure?

There are various sorts of algorithms. Some important algorithms are: Sorting Algorithms, Searching Algorithms, Hashing, Dynamic Programming, String Matching and Parsing, Greedy Algorithm, Brute Force Algorithm, Recursive Algorithm, Backtracking Algorithm, Divide and Conquer Algorithm.
