Map data structure: How does a Hash Table work?
Показать описание
What is a Map? How does a hash table work? In this short video I explain it.
Map is one of the most used data structures and core to Computer Science Fundamentals.
On this video I talk briefly about what is a map, how does a hash table work (or in specifically in Java, how a hashmap works) and how to reason about it. This is a question typically asked during technical interviews and it builds on top of many other data structures.
If you are in a hurry and want to get a grasp of basic CS Fundamentals quickly, specially to review topics for technical interviews, I think this video might be useful to you.
Here are some books I recommend to learn more about the topics I've talked so far (this are personal recommendations, but I might receive money based on clicks or purchase):
Tell me what you think, if you like it or not, or if I missed something you'd like to see.
