PrepInsta Data Structures & Algorithms
Data Structures and Algorithms (DSA) form the foundation of efficient programming. A data structure is a way of organizing and storing data so it can be accessed and modified easily. An algorithm is a set of step-by-step instructions used to solve a specific problem or perform a task.

Data Structure and Algorithms comprises of two words –
- Data Structures
- Algorithms
What are Data Structures ?
Data Structures are special ways of organizing and storing data in a computer so that we can use it easily and efficiently.
- Think of them like containers or shelves where you keep your things in a neat order – like a list, a stack of plates, or a queue at a ticket counter.
- Different types of data structures help solve different kinds of problems better.
What are Algorithms ?
Algorithms are step-by-step instructions or a set of rules to solve a problem or complete a task.
- It’s like a cooking recipe that tells you exactly what to do, one step after another, to make a dish.
- In computer science, algorithms help computers perform tasks like searching, sorting, or finding the best solution to a problem.

Trees
Trees are one of the most crucial topics in Data Structure which are a little complicated than the other topics in C. Questions from this topic are often asked in college semester examinations as well as Company interviews and online tests which are of a good difficulty level and have more weight age than other questions.

Hey Harshitha! Please reach out to us at 8448440710.
please add prepinsta pages of theory of graphs hashing heap backtracing dynamic programming.
pls do data structure and algorithms topics in python for free
Why there is no python?
implementation in python does not boost logics as c c++ or java but rather you can practice in any lang if you know the working of the algorithm
