There are a lot of computer science graduates and programmers applying for programming, coding, and software development roles at startups like Uber and Netflix and big organizations like Amazon, Microsoft, and Google. They are also quite popular on service-based companies like Infosys, TCS, or Luxsoft, but many of them have no idea of what kind of programming interview questions to expect when you’re applying for a job with these companies. Things
have also changed a lot in the last few years and coding interviews
have become tougher. Now you need to go through a couple of coding
interview rounds but you also need to prepare for System design problems which wasn’t normal in the last decade.
Top 10 Algorithms books Every Programmer Should Read
Algorithms are language agnostic, and any programmer worth their salt should be able to convert them to code in their programming language of choice. Unfortunately, I have come across several programmers who are REALLY good at programming languages like Java or Python, like know minor details of API and language intricacies but have very poor knowledge of the fundamentals of Algorithms and Data Structures. Just ask them to implement any popular sorting algorithms like quicksort or merge sort, and they will fall apart. If you expect them to know more advanced and sophisticated algorithms like String processing algorithms, graph algorithms, tree traversal, or greedy algorithms, be ready to check on Interviews; otherwise, you might end up with some surprises.
How to implement Level Order Traversal of Binary Tree in Java? Example Tutorial
Hello guys, if you have worked in Java then you know that binary tree is one of the essential data structure and quite an important one for programmers, I even mentioned that on my 10 essential data structures for programmers articles. Binary tree related question are also quite common on coding interviews and we are going to see one today but before that, let's revise what is binary tree? Binary trees are hierarchical data structures composed of nodes, each having at most two children: a left child and a right child. Traversing a binary tree in level order involves visiting nodes level by level, starting from the root.
