7 Must Know Algorithms for Your Next Coding Interview

I aced every interview I appeared for.

There are thousands of questions that the interviewer may ask in a coding interview and a major part of them consists of Data Structures and Algorithms.

Within data structures and algorithms also, there are thousands of questions available. No one solves all of them and that is also not expected in an interview.

The key distinction is that you don’t need to solve all of them or memorize them but understand the fundamental techniques that are common in most of the questions. Every question is more or less a variation of another and there are some algorithms that give birth to the majority of these questions.

We will discuss the top 7 algorithms you must prepare for your next coding interview.

1. Data Structures and Their Implementation

There are about 7 popular data structures that everyone expects you to know if you are a developer. They are —

1. Arrays
2. Linked Lists
3. Stacks
4. Queues
5. Trees
6. Graphs
7. Hash Tables/Sets
