Algorithms and Data Structures in C#: Complete Tutorial from Udemy

Why learn about data structures and algorithms?

Algorithms and data structures constitute the fundamentals of programming.

Good understanding of algorithms and data structures is one of the most important requirements for a great number of work positions. You'll have to solve many problems related to algorithms and data structures at coding interviews. Indeed, you can live without an understanding of algorithms and data structures, in general. However, you can do that until you face a real problem which requires to choose right data structures and implement custom algorithms. If you haven't ever faced such problems, believe me, this is just a matter of time. One day, you'll face such a problem and if you don't understand algorithms and data structures in depth, you'll feel yourself ashamed and helpless. You'll be stuck.
If you're not good at algorithms and data structures, you'll never pass a coding interview in a decent company. Almost all the companies prefer to hire those developers who have good understanding of algorithms and data structures, remember that. Do not delay the study of fundamental concepts.
Better hardware is not a solution for all the performance-related problems. Sometimes, you need to write software for very slow devices. And that very often depends on the budget of a customer, by the way, so you don't have a control over it.
You'd better to understand what's going on under the hood at least one level in-depth. Indeed, if you don't understand how List works, sometimes you'll make sub-optimal or completely wrong decisions.
