The cost of every singly linked list operation in one place — big-O, and the traps that bite in practice. We build the complexity table ...

How graph representations actually live in memory — the byte-level layout behind the abstraction. We map the abstract picture ...

Close the loop and the special cases disappear: a ring has no NULL to guard, so a lap simply wraps. We build a ring from a single ...

A tight recap of searching: the mental model, the operations, and the costs — everything worth keeping. The essential takeaways ...

Before the how, the why: what problem dynamic arrays solve, and what it costs you to get them wrong. We start from a concrete ...

A plain, precise definition of a graph — and the one idea everything else follows from. We define it exactly, picture it, and pull out ...

Append on dynamic arrays — adding to the end, and when it stays cheap. This lesson shows exactly what happens, step by step, ...
