Statements of C++

By Ashiq
  Statements A computer program is a sequence of instructions that tell the computer what to do. A  statement  is a type of instruction that causes the program to  perform some action . Statements are by far the most common type of instruction in a C++ program. This is because they are the smallest independent unit of computation in the C++ language. In that regard, they act much like sentences do in natural language. When we want to convey an idea to another person, we typically write or speak in sentences (not in random words or syllables). In C++, when we want to have our program do something, we typically write statements. Most (but not all) statements in C++ end in a semicolon. If you see a line that ends in a semicolon, it’s probably a statement. In a high-level language such as C++, a single statement may compile into many machine language instructions. For advanced readers There are many different kinds of statements in C++: Declaration statements Jump statem...

[Solution] Fibsieve's Fantabulous Birthday C/C++/python

By Ashiq
  Fibsieve's Fantabulous Birthday                English              Fibsieve had a fantabulous (yes, it's an actual word) birthday party this year. He had so many gifts that he was actually thinking of not having a party next year. Among these gifts there was an  N x N  glass chessboard that had a light in each of its cells. When the board was turned on a distinct cell would light up every second, and then go dark. The cells would light up in the sequence shown in the diagram. Each cell is marked with the second in which it would light up. 25 24 23 22 21 10 11 12 13 20 9 8 7 14 19 2 3 6 15 18 1 4 5 16 17 In the first second the light at cell (1, 1) would be on. And in the 5th second the cell (3, 1) would be on. Now, Fibsieve is trying to predict which cell will light up at a certain time (given in seconds). Assume that  N  is large enough. Input Input starts with an integ...

Codeforces Global Round 22

By Ashiq
  Codeforces Global Round  22 Hello, Codeforces Addicts! On  Friday, September 30, 2022 at 20:35 UTC+6  we will host  Codeforces Global Round 22 . Codeforces Global Round  22  is the  2 ⋅ 2 = 4 2 ⋅ 2 = 4 -th round of a 20 22  series of  Codeforces Global Rounds . The rounds are open and rated for everybody. The prizes for this round: 30 best participants get a t-shirt. 20 t-shirts are randomly distributed among those with ranks between 31 and 500, inclusive. The prizes for the 6-round series in 20 22 : In each round top-100 participants get points according to the  table . The final result for each participant is equal to the sum of points he gets in the four rounds he placed the highest. The best 20 participants over all series get sweatshirts and place certificates. Thanks to XTX, which in 20 22  supported the global rounds initiative! The problems were written and prepared by  antontrygubO_o ,  Milesian  and m...

Callback function in JavaScript

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

By Ashiq

# 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`....

Bitwise Operators in C/C++

By Ashiq

  Bitwise Operators in C/C++ In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C. The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. The | (bitwise OR) in C or C++ takes two numbers as operands and does OR on every bit of two numbers. The result of OR is 1 if any of the two bits is 1. The ^ (bitwise XOR) in C or C++ takes two numbers as operands and does XOR on every bit of two numbers. The result of XOR is 1 if the two bits are different. The << (left shift) in C or C++ takes two numbers, the left shifts the bits of the first operand, and the second operand decides the number of places to shift. The >> (right shift) in C or C++ takes two numbers, right shifts the bits of the first operand, and the second operand decides the number of places to shift. The ~...
