Software Engineering Implementing Binary search in C++ We have explained in depth how to implement Binary Search in C++. We have covered 3 approaches: Recursive implementation, Iterative implementation and using STL functions.
Algorithms Kadane's Algorithm for largest subarray sum Kadane's Algorithm is commonly known for Finding the largest sum of a subarray in linear time O(N). We have presented 3 variants of Kadane's Algorithm along with in-depth explanation of basic ideas.
Software Engineering Reducing Time limit of code in Java In this article, we have explored how to make a Java code execute faster by handling Input and Output better. The ways we presented are Scanner class, BufferedReader class, User-defined FastReader Class and Reader Class.
Algorithms Binary GCD Algorithm Binary GCD algorithm or Stein's algorithm is an algorithm that calculates two non-negative integer's largest common divisor by using simpler arithmetic operations than the standard euclidean algorithm and it reinstates division by numerical shifts, comparisons, and subtraction operations.
Software Engineering String Class (java.lang.String) in Java The java.lang.String class provides a lot of methods to work on string. By the help of these methods, we can perform operations on string such as trimming, concatenating, converting, comparing, replacing strings etc. We have explored it in detail.
Software Engineering Auto Key Cipher Autokey (Autoclave) Cipher is a Symmetric polyalphabetic (Polyceaser) substitution cipher. This algorithm is about changing plain text letters based on secret key letters.
Software Engineering Play Fair Cipher Play Fair Cipher was the first practical digraph substitution cipher. In play fair cipher unlike traditional cipher, we encrypt a pair/digraph of alphabets (digraphs) instead of a single alphabet.
Algorithms Finding the Largest Element in an Array We are given an integer array of size N or we can say number of elements is equal to N. We have to find the largest/ maximum element in an array. The time complexity to solve this is linear O(N) and space complexity is O(1).
Software Engineering How is 'this' reference in Java used? The 'this' keyword in Java is a reference ( which means it manages some relation ) to the current object where it is called. We have presented 6 usage of this keyword which includes referring to current class instance variable and much more.
Machine Learning (ML) Bernoulli Naive Bayes Bernoulli Naive Bayes is used for discrete data and it works on Bernoulli distribution. The main feature of Bernoulli Naive Bayes is that it accepts features only as binary values like true or false, yes or no, success or failure, 0 or 1 and so on.
Software Engineering begin() and end() in Array C++ STL In this article, we have explored begin() and end() functions in Array container of C++ STL in depth. We have covered the basic idea of iterators as well as both functions deal with iterators.
Software Engineering Types of CSS layout In this article, we have deep dived into the CSS layouts. CSS layouts are mainly used to enhance the beauty of the website and make the website responsive. The various CSS layouts are Normal flow, Flexbox, Grids, Floats, Positioning and Multiple-column layout.
Machine Learning (ML) How I mastered Machine Learning as a Fresher? This is a complete guide by Shaurya Bhandari who went through the basics of Machine Learning as a fresher in College on his own. He explains the path he had taken so that you can follow it as well.
Software Engineering Different ways of Initializing multimap in C++ We have covered the different ways to initialize multimaps which includes inserting elements using make_pair, pair, initializer list, using another multimap, copy constructor and emplace_hint().
Algorithms Postman Sort Postman sort works by sorting the integers of an array from their most significant digits to their least significant digits. It is a variant of radix sort.
Software Engineering Counter Objects in Python In this article, we have explored Counter Objects in Python in depth. Counter is a part of collections module and is a subclass of a dictionary which is used to keep a track off elements and their count.
Machine Learning (ML) VGG-11 Architecture In this article, we have explored VGG-11 model architecture which has 11 layers namely 9 Convolution layers (with 5 MaxPool layers), 2 Fully connected layers and an output layer with softmax activation.
Machine Learning (ML) The Inception Pre-Trained CNN Model This is an overview of the Inception pre-trained CNN model along with a detailed description about its versions and network architectures including Inception V1, V2, V3, V4 and Inception-ResNet.
