The OOP Revolution: Building Better Software with Relatable Tools

By Ashiq
  The OOP Revolution: Building Better Software with Relatable Tools In the world of code, where every line tells a story, Object-Oriented Programming (OOP) has become the language of innovation. Let’s take a closer look at how OOP transforms our understanding of what we build — not just how, but why. At its core, OOP is about organizing code into objects. Imagine each object as a unique entity in your software, like a student, a teacher, or a recipe. These objects have attributes (what they contain) and methods (what they do). It’s more than just writing code — it’s about building systems that grow and evolve with you. Encapsulation hides complex data within objects, making it easier to maintain. Inheritance lets you reuse code from other classes, saving time and effort. Polymorphism enables objects to be treated as different types, allowing for flexible behavior. These principles aren’t just good practice — they’re the foundation of modern software design. If you’re a developer, O...

  ICPC Dhaka Regional Preliminary Contest 2022 Hosted By Green University of Bangladesh Problem A: A Game with Grandma Setter: Shafaet Ashraf Tester & Alter writers: Nafis Sadique Aleksa Plavsic Arghya Pal Problem type: Game Theory, DP Solution idea: If you're familiar with Grundy Numbers, you can use the divide and conquer technique to solve it. To do this, loop through the columns of the grid and place a box in all possible positions. Whenever a box is placed, it divides the whole grid into two parts. Solve each sub-problem recursively by calculating the Grundy number. The base case is when the grid size is less than 1. This solution has a time complexity of O(N^3) and will pass the time limit. Problem B: Transform the Array Setter: Raihat Zaman Neloy Tester & Alter writers: Md. Mahbubul Hasan H. M. Ashiqul Islam Muhiminul Islam Osim Problem type: Number theory, finding prime divisors Solution idea: For the first type of transformation - Let's find two sets of primes ...

Using Generic in TypeScript about types in the Code

# Using Generic in TypeScript about types \<T> in the Code ## Question 1: Here what is this <T> means? ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` ## Answer 1: In the code snippet you've provided, `<T>` is a **generic type parameter** in TypeScript. It allows you to write a function that can work with any type of object while still maintaining that object's specific type information. When you use the function `addID`, you can pass in an object of any type, and TypeScript will understand that the returned object will be of the same type as the input, plus the additional `ID` property. Here's a breakdown of how it works: ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` - `<T>`: Declares a generic type `T`. - `(obj: T)`: Indicates that the function takes an argument `obj` of type `T`....

 ⭕ Whiteboarding interviews are a common way of assessing the technical and non-technical skills of candidates for software development positions. They involve solving a coding problem or designing a system on a whiteboard, either in person or virtually, while explaining your approach and reasoning to the interviewer.  ⭕ Some of the benefits of whiteboarding interviews are that they can test your problem-solving ability, communication skills, and coding proficiency in a realistic scenario. They can also help you demonstrate your creativity, collaboration, and passion for the role. However, some of the drawbacks of whiteboarding interviews are that they can be stressful, artificial, and biased. They can also favor memorization over understanding and overlook other aspects of your skills and experience.  ⭕ If you want to ace a whiteboarding interview, you should practice beforehand, prepare for the interview setting, set objectives and expectations, create a good candidate ...
