Dsa Heaps in Dsa

A heap is a special binary tree that keeps the smallest (min-heap) or largest (max-heap) element at the root. Push and pop are O(log n), and peeking at the top is O(1). It is the go-to structure for a priority queue — always serve the most urgent item next.

Heaps shine for "top-K" and "K-th largest/smallest" problems and for merging sorted streams. Python's heapq module is a min-heap; for a max-heap, push negated values. Building a heap from n items is O(n).
