Before we can properly discuss data structures and the related performance, a basic understanding of time complexity (and specifically the big O notation) is required. No need to worry! The concept is really simple, but without it, we cannot easily explain the performance characteristics of operations.
Once the big O notation is clear, we will discuss the basic data structures:
