Number of Provinces - LeetCode #547 | Python Solution (with JavaScript, Java, and C++ Codes)

Let's solve Number of Provinces, LeetCode #547! This is LeetCode daily coding challenge on June, 4th.

Welcome to my coding tutorial video on solving the Number of Provinces problem from LeetCode! In this video, I'll guide you through the step-by-step process of solving the problem using Python, and I'll also provide the solution codes in JavaScript, Java, and C++ for your reference.

The Number of Provinces problem, also known as "Friend Circles," challenges you to determine the number of connected provinces in a given matrix. Each province represents a node, and if two nodes are connected, they belong to the same province. Solving this problem requires a solid understanding of graph theory, data structures, and algorithms.

In this tutorial, we'll start by understanding the problem statement and its requirements. Then, I'll demonstrate a Python implementation of the solution, explaining the logic behind it and highlighting key data structures and algorithms used. You'll be able to follow along easily, even if you're a beginner.

To cater to a broader audience, I have also included the solution codes in JavaScript, Java, and C++. These additional solutions will help viewers who are comfortable with different programming languages. You can find the code snippets in the video description or the pinned comment below.
