Today in less than 20 minutes, we'll explore what maps are and how they work under the hood. We'll talk about the differences between treemaps, hash maps, and hash tables. We'll dig pretty in-depth...By the end of the episode, you'll understand how to implement hash tables using an array, hash function, and a linked list!

Today we'll look into static and dynamic systems. We'll discuss what does it mean for a programming language or a framework to be static or dynamic. In the second part of the podcast, we'll focus on some of the properties of static systems and how they can help in better compile-time optimizations, development experience, and more!

The chances are that the information from this episode will come in handy to you during a coding interview and likely in real life! In this episode, you'll learn the topological sort algorithm. Along the way, you'll understand what's a dependency graph and how topological sort operates on this data structure. We'll also discuss a few real-life examples where I had to implement topological sort myself!

Have you ever been frustrated during interviews thinking that your interviewer expects you to have memorized a bunch of sorting algorithms you'd never need in real life? In this episode of the podcast learn how to approach such situations. In performance critical systems you may have to implement an efficient sorting yourself. Learn how to beat the built-in algorithm in a few lines of code!

Today you'll learn how at runtime, you can enhance the behavior or existing objects using the decorator pattern. In this episode, we'll discuss the advantages of decorators over inheritance and look at two examples from real-life - implementing a network communication protocol and enriching user interface components.

In this episode, we'll discuss graphs. You'll learn how this data structure looks like and what are its applications. Later on, we'll talk about algorithms for traversing graphs. You'll understand how breadth-first search and depth-first search work and when you should use one instead of the other. Topics we'll also touch on are chromatic graphs and finding the shortest path.

In this episode, we'll discuss two fundamental data structures in computer science - arrays and linked lists. Their understanding is essential not only in your day to day job but also for performing well on your next coding interview. We'll discuss implementation details for both data structures, and we'll talk about when it's better to choose one instead of the other. Along the way, we'll touch on memory hierarchy, caching locality, and different interview problems.

Today we'll discuss partial application and currying. By the end of the episode, you'll understand what these two different concepts are how they are different from each other, and where you can apply them in practice. In between the episode, we'll also talk about the brilliant computer scientist Haskell Curry, and we'll mention the Curry-Howard isomorphism
