What is Data Structures and Algorithms?

Data structures and algorithms are an essential part of computer programming. Data structures define the way to store data efficiently and easily. This data can then be called upon faster for analysis or result. Data structures include Float, Boolean, Char, Tree, Graph, Stack, Queue and more. On the other hand, an algorithm is a collection of instructions defined in a specific order to perform a specific task. Even though the Algorithm is not the complete program, it is the core logic. Algorithms are to speed up the execution process and reduce the memory requirement.

What are the Prerequisites for learning Data Structures and Algorithms?

If you wish to learn data structures and algorithms, one of the prerequisites is to have a core understanding of C language, as it helps you gain insights into data structures. One can also invest some time in programming in Java, C++ or Python. Also, data structures algorithm programming requires basic knowledge of concepts such as loops, inheritance, polymorphism, arrays, strings, memory allocation and pointers. A rudimentary understanding of mathematics and reasoning helps you grasp concepts even better.

Why Should you learn Data Structures and Algorithms?

A basic program has three steps; an input, a process and an output. To make the program fast and efficient, it needs to be optimized. This is where Data structures and Algorithms pitch in. Data structures stores the data in a structured format so that it can be easily processed and displayed. Algorithms on the other hand help in reducing memory space and process the data swiftly. As the program complexity increases, Data structures and algorithms become very crucial in improving the performance of the program.

How can Hackr.io help you find the best Data Structures and Algorithm tutorials?
