Depth First Search Algorithm In Python (Multiple Examples)

Introduction Graphs and Trees are one of the most important data structures we use for various applications in Computer Science.They represent data in the form of nodes, which are connected to other nodes through ‘edges’. Like other data structures, traversing all the elements or searching for an element in a graph or a tree is one of the fundamental operations ...

NumPy Where Tutorial (With Examples)

Looking up for entries that satisfy a specific condition is a painful process, especially if you are searching it in a large dataset having hundreds or thousands of entries. If you know the fundamental SQL queries, you must be aware of the ‘WHERE’ clause that is used with the SELECT statement to fetch such entries from a relational database that ...

Caesar Cipher In Python (Text Encryption Tutorial)

Cryptography deals with encrypting or encoding a piece of information (in a plain text) into a form that looks gibberish and makes little sense in ordinary language.This encoded message(also called ciphertext) can then be decoded back into a plain text by the intended recipient using a decoding technique (often along with a private key) communicated to the end-user. Caesar Cipher is ...

NumPy Loadtxt Tutorial (Load Data From Files)

In a previous tutorial, we talked about NumPy arrays and we saw how it makes the process of reading, parsing and performing operations on numeric data a cakewalk. In this tutorial, we will discuss the NumPy loadtxt method that is used to parse data from text files and store them in an n-dimensional NumPy array. Then we can perform all sorts of ...
