A heap gives you O(1) access to the minimum (or maximum) element and O(logn) insertions and deletions. Use a heap when you need to repeatedly find the smallest/largest element, or when you need to maintain the top k elements. In this section, you'll learn the "Top K" pattern and streaming problems. These are common in system design discussions too.
