Exponentiation Solution C++ : CSES Problem Set

By Ashiq
CSES Problem Set Exponentiation TASK SUBMIT RESULTS STATISTICS HACKING Time limit: 1.00 s Memory limit: 512 MB Your task is to efficiently calculate values a^b modulo 10^9+7. Note that in this task we assume that 0^0=1. Input The first input line contains an integer n: the number of calculations. After this, there are n lines, each containing two integers a and b. Output Print each value a^b modulo 10^9+7. Constraints1 \le n \le 2 \cdot 10^5 0 \le a,b \le 10^9 Example Input:3 3 4 2 8 123 123 Output:81 256 921450052 Link to this code: https://cses.fi/paste/ced3e665267b063471beea/ #include <bits/stdc++.h> #include <iostream> #include <iomanip> #include <cmath> #include <string> #define MOD 1000000007 #define ell cout<<endl #define el endl #define pi 3.14159 #define forn(i, n) for (int i = 0; i < int(n); i++) #define ll long long #define ull unsigned long long #define ld long double #define vll vector<ll> #define pll pair<ll,ll> #de...

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 ...
