Algorithms Tim Sort Tim Sort is a hybrid stable sorting algorithm that takes advantage of common patterns in data, and utilizes a combination of an improved Merge sort and Binary Insertion sort along with some internal logic to optimize the manipulation of large scale real-world data.
Software Engineering Creating JWT Authentication in REST API in Flask JSON Web Token is a string which is sent in HTTP request from the browser to the server to validate authenticity of the client. We have demonstrated how to create JWT Authentication in REST API in Flask.
Algorithms Algorithm to find the maximum power of N that divides M factorial (M!) We are given two numbers M and N. Our aim is to find the highest power of N that divides Factorial of M (M!). First we have discussed about the Brute Force approach and then we will be discussing this problem using Legendre’s formula.
Machine Learning (ML) Adversarial Machine Learning Adversarial Machine learning is the technique which involves applying different methods in order to construct or generate examples that are meant to fool the machine learning model.
Machine Learning (ML) K means vs K means++ The main difference between K Means and K Means++ lies in the selection of the centroids around which the clustering takes place and k means++ removes the drawback of K means which is it is dependent on initialization of centroid.
Software Engineering Viewing the history of git commits (git log) In this article, we have explored how we can view the history of git commits that is using git log. We have explored several different options that can be used along with "git log".
Software Engineering Undoing Local Changes in Git when in the Working area or Staging area In this article, we have explored how to can undo Local Changes in Git when in the Working area or Staging area. We have demonstrated this with example and complete understanding.
