CS Fundamentals: Arrays & Linked Lists
Test your knowledge of arrays and linked lists — the two most fundamental data structures and the trade-offs between them.
Questions cover time complexity of access, insertion, and deletion, the difference between singly and doubly linked lists, and when to choose one structure over the other.
Almost every other data structure builds on these two — see how solid your fundamentals are.
