Working with Set in Java like a master

Set is a data structure that is used as a collection of objects. Java supports it through its Java Collection library.

Importance of Loss Function in Machine Learning

A loss function is a measure of how good your prediction model does in terms of being able to predict the expected outcome(or value).

Software Engineering

Different ways to take input in C++

We are going to discuss how we can get different types of information from the user like from local files and interactive input using cin

Software Engineering

Using if else if statement in C

if else if is a conditional statement that allows a program to execute different code statements based upon a particular value or expression. It is natively supported in C programming language

Algorithms

Shortest Common SuperSequence 【O(M*N) time complexity】

Given two strings X and Y, the supersequence of string X and Y is such a string Z that both X and Y is subsequence of Z.

Algorithms

All Valid Word Breaks of a Sentence 【O(2^N) time complexity】

We are given with a valid sentence without any spaces and we are given with a dictionary of words. We need to print all the possible ways to break the sentence so that all the breaked words belongs to the dictionary.

Algorithms

Word Break Problem 【O(n * s) time complexity】

In this problem we are given with a string and a dictionary of words, we need to find if the string can be segmented to words so that all the segmented words are present in the dictionary.

Understanding Singleton Design Pattern in C++ with 4 techniques

Singleton pattern in C++ is a design pattern which prevents multiple objects of a class to exist. This is a very useful and widely used design pattern

Software Engineering

Null Object Design Pattern in C++

Null object pattern is a design pattern that simplifies the use of dependencies that can be undefined. This is achieved by using instances of a concrete class that implements a known interface, instead of null references.

Software Engineering

Understanding Observer Pattern in C++ in depth

The Observer Pattern is a design pattern where changes in one object can be notified to other objects. This is important as with this, we can use objects that have dependency

Software Engineering

Understanding Abstract Factory Pattern in C++ with an example

Abstract factory pattern provides a framework that allows to create objects that follows a pattern. So at runtime, abstract factory is coupled with any desired factory which can create objects of desired type.

Converting colored images (RGB) to grayscale using Autoencoder

We built an autoencoder from scratch in TensorFlow to generate the grayscale images from colored images.

Software Engineering

Learn about the internals of a Python Object

In Object Oriented Python, it is useful to understand the internal things of an object or a class or a class instance. It can help in understanding the internal logic and in debugging.

Algorithms

Stooge Sort

Stooge sort performs sorting in first 2/3 part and then it performs sorting in last 2/3 part. After that, sorting is done on first 2/3 part to ensure the array is sorted.

Software Engineering

Write Custom/ User-defined exceptions in Java

Custom Exceptions: These exceptions are not defined in Java librairies, but can be defined by us to handle customized error situations. Example: Suppose, our banking transaction program should raise exception for debit from an account with zero balance
