Heaps & Priority Structures
Module Contents
Understand the Binary Heap data structure. Learn how to map a Tree to an Array and master Sift Up/Down.
Why build a Heap in O(N)? Learn the Sift Down optimization and Heap Sort algorithm.
Solve Top K Elements. Use Priority Queues for Task Scheduling. Learn the pattern.
Solve the Median from Data Stream problem. Use the Two Heaps pattern to find the median in O(1).
Master Dijkstra’s Shortest Path Algorithm. Understand how a Priority Queue makes graph traversal efficient.
Staff Level: How malloc uses Heaps. Understanding the Free List, Fragmentation, and the Buddy System.
Review Binary Heaps, Priority Queues, Heap Sort, and Dijkstra. Flashcards and Cheat Sheet.
