Depth-first search is a traversal technique in which we traverse a graph and print the vertices exactly once. In this article, we will study and implement the depth-first search for traversing graphs in python. Recommended read: Implementing a graph in Python What is the Depth-First Search Algorithm? In a depth-first search, we traverse each vertex …
Breadth-first search is a traversal technique in which we traverse a graph and print the vertices exactly once. In this article, we will study and implement the breadth-first search for traversing graphs in python. What is the Breadth-First Search Algorithm? In breadth-first search, we traverse each vertex of the graph exactly once by starting from …
In this article, we will discuss how to perform different graph operations. Graphs are nonlinear data structures that consist of vertices and edges. They’re used to represent maps between cities, social media connectivity of users, and connectivity of web pages, etc. Working on Graph Operations If you have not studied the implementation of a graph, …
A graph is a data structure used to illustrate connections between two objects. A simple example of a graph is a geographical map in which different places are connected by roads. In this article, we will study the theoretical aspects of a graph data structure. Additionally, we will implement a graph using two different methods. …
In this article, we will learn more about Min Heap (known as heap queue in Python). We have already learned about Heap and its library functions (in heapq module) in python. We will now learn about min-heap and its implementation and then look at the Python code for implementing the heapify, heappush and heappop functions …
