Stacks
Hash Tables
A data structure that store data in key-value pairs and provides fast insertion, deletion and searching.
Linked Lists
Is very similar to array, at least conceptually, to an array.
Arrays
There are two types of arrays. Static and dynamic ones.
Logarithm
It’s mathematical concept which is very often used in Computer Science in context of algorithms complexity, it’s even sounds similar 😀
