Python’s heapq module offers a highly efficient min-heap implementation. A min-heap, by definition, keeps its smallest element at the root (index 0). While adding (heappush) and removing (heappop) elements are common operations, frequently you’ll need to examine the smallest element without altering the heap’s structure—a process we call “peeking.” This…

Efficient List Deduplication in Python
Removing duplicate elements from a list, a process called deduplication, is a common task in Python. The best approach depends on whether you need to preserve the original order of elements. This article explores two efficient methods: one prioritizing speed and the other preserving order. Table of Contents Deduplicating a…

Efficient Priority Queues in C#: SortedSet vs. Min-Heap
A priority queue is a fundamental data structure that extends the functionality of a standard queue by assigning a priority to each element. Unlike a FIFO (First-In, First-Out) queue where elements are processed in the order they arrive, a priority queue dequeues (removes) elements based on their priority. The highest-priority…
