Frequently asked questions

What does DSA mean in coding?

It stands for data structures and algorithms. Data structures are ways of storing information such as arrays, trees and hash tables, and algorithms are the procedures that operate on them efficiently.

Why do tech interviews focus on DSA?

The problems are short, self-contained and comparable across candidates, so companies use them to test problem-solving and reasoning about efficiency. Critics point out they test a narrow skill that does not always match day-to-day work.

What is the difference between a data structure and an algorithm?

A data structure is how information is arranged, such as a linked list or a hash map. An algorithm is the sequence of steps used to solve a problem, and it usually depends on a well-chosen data structure to run quickly.
