  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 ...

Callback function in JavaScript What is a callback function in JavaScript? A callback function is a function that is passed as an argument to another function and is executed after the first function has completed its task. Callback functions are useful for handling asynchronous events, such as network requests, file operations, or timers. For example, you can use a callback function to display the result of a calculation after the calculation is done. Callback function in JavaScript Here is a simple example of a callback function in JavaScript: // Define a function that takes a callback as an argument function sayHello (callback) { // Do some task console .log ("Hello, world!"); // Invoke the callback function callback (); } // Define another function function sayGoodbye () { // Do some task console .log ("Goodbye, world!"); } // Call the first function and pass the second function as a callback sayHello (sayGoodbye); // The output will be: // Hello, wo...

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`....
