Breadth First Search Algorithm Explained With C++ Examples

Показать описание

In this video I explain the idea of the breadth first search algorithm in C++ with an example.

I have linked some problems that you can go and solve after watching this video.

DONT CONSUME ANYMORE VIDEOS WITHOUT PRACTICING WHAT YOU HAVE LEARNED.... Otherwise you will not learn and embed the knowledge in you brain.

These problems are the basic must know, and should get you to understand breadth first search easily.

(make sure you solve using breadth first search)
even though there are other solutions.

List of Problems:

Same Tree

Binary Tree Level Order Traversal

Symmetric Tree

Number of Islands

Welcome to our C++ algorithm series! In this video, we'll dive into the Breadth First Search (BFS) algorithm, a fundamental graph traversal technique used to explore graphs efficiently. If you're looking to understand graph traversal and how to implement BFS in C++, this video is for you.

BFS is an essential algorithm for solving problems like finding the shortest path, detecting connected components, or exploring all nodes in a graph. In this comprehensive tutorial, we'll break down the BFS algorithm step by step and show you how to implement it using C++.

Throughout the video, we'll start with an intuitive explanation of BFS and its underlying principles. We'll demonstrate how the algorithm explores a graph layer by layer, ensuring that all nodes at a given depth are visited before moving deeper into the graph.

Using clear and concise C++ code example, we'll guide you through the implementation of BFS. You'll learn how to represent a graph in C++, and use queue data structure to keep track of visited nodes and explore their neighbors.

We'll also cover important concepts such as marking nodes as visited, tracking distances, and handling edge cases. Along the way, we'll discuss time and space complexity, and provide tips for optimizing your BFS implementation.

By the end of this video, you'll have a solid understanding of the Breadth First Search algorithm and be able to apply it to solve a wide range of graph-related problems in C++. So, join us in this tutorial and master the art of graph traversal with Breadth First Search in C++! With this Breadth First Search Algorithm Explained With C++ Examples. You will know how to solve breadth first search algorithm problems. The way breath first search is explained is super important. Here I use C++ Examples to showcase the breadth first search algorithm. And I explain the important concepts of this algorithm.
