403. Scientific Problem - C++ / C - Solution - Codeforces ACMSGURU problemset

By Ashiq
403. Scientific Problem Time limit per test: 0.25 second(s) Memory limit: 65536 kilobytes input: standard output: standard Once upon a time Professor Idioticideasinventor was travelling by train. Watching cheerless landscape outside the window, he decided to invent the theme of his new scientific work. All of a sudden a brilliant idea struck him: to develop an effective algorithm finding an integer number, which is x times less than the sum of all its integer positive predecessors, where number x is given. As far as he has no computer in the train, you have to solve this difficult problem. Input The first line of the input file contains an integer number x (1 ≤ x ≤ 109). OutputOutput an integer number — the answer to the problem. Example(s) sample input sample output 1 3 sample output 2 5 Solution Code: C++ #include <iostream> using namespace std ; // solved int main () { int x ; cin >> x ; cout << 2 * x + 1 << endl ; return 0 ; } Solu...

A. How Much Does Daytona Cost? Problem - A - Codeforces - Codeforces Round 900 (Div. 3) Solving the Most Common Element Subsegment Problem in C++ Introduction: In the world of programming, problem-solving is a fundamental skill. It involves taking a complex task and breaking it down into smaller, manageable steps. In this blog post, we will dissect and solve a code problem that involves finding if a specific element exists in an array. The problem statement is as follows: Problem Statement: You are given an array of integers and an integer K. The task is to determine whether K exists in the given array. You will be provided with multiple test cases, each containing an array and a value of K. For each test case, you need to output "YES" if K is found in the array and "NO" otherwise. Solution: Let's break down the problem into steps and implement a solution in C++.Read the number of test cases (t) from input. Enter a loop that runs t times, one iteration for eac...

Codeforces round #900 (Div.3) Editorial

By Ashiq
  Codeforces round #900 (Div.3) Editorial Thank you for participating in the first ever Serbian Div. 3 Codeforces round! Sorry Before the editorial, we are sorry for the big gap between problems C and D. This was the first round we ever created (except for  wxhtzdy ). We are striving to become better problem-setters and create more balanced problems-sets in the future. Also a massive thanks to  Vladosiya  for giving us a chance to create a divison 3 round! 1878A - How Much Does Daytona Cost? Problem was authored and prepared by Author:  wxhtzdy Prepared by:  ognjentesic ,  AndrewPav ,  AlphaMale06 Hints Hint 1 When is the answer definitely "NO"? Hint 2 What happens if there is no element equal to  k �  in the array? Hint 3 What happens if there is an element equal to  k �  in the array? Tutorial 1878A - How Much Does Daytona Cost? It's enough to check if there even exists the element equals to  K � , since  K �  ...

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`....

 ⭕ 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 ...
