5 lessons in Data Structure & Algorithms

Each lesson pairs one topic with a hand-picked video, trimmed to the part that teaches it.

About this subject

Queues are the strongest single topic (queue using array program, enqueue/display using linked list, simple-queue limitation); add bubble sort with a worked example and BFS/DFS algorithms to cover Part C. Part A is very easy two-option fill-ins.

    Trees and graphs: BFS and DFS

    Must study for the exam (×4 · A3, A4, B2, C2 2 + 2 + 5 + 15 marks · fill-in, short note, algorithm).
