// Given a sorted array A (sorted in ascending order), having N integers,
// find if there exists any pair of elements (A[i], A[j]) such that
// their sum is equal to X.
//
// Input: A = [2,3,4,5,6,7,8,9], k= 10
// Output: true
// NOTE: We slightly changed the question and the output in the video. We're returning pair indexes as an array.

Who Am I

Non-Work

Above all, I'm a human being. I have a variety of strengths and weaknesses, emotional ups and downs, and I make mistakes.

I spend a lot of time thinking about thinking. I'm curious about the World and how it works, which drives me to study things way outside the scope of my career. Currently, I'm into complexity science. In general, personal development is an important part of my life. My personal motto is "always leveling up" because I'm always working on something to level myself up in some way.

georgebullock

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

FRONTEND INTERVIEW QUESTIONS

1 - Which version control systems are you familiar with? How do you share code between projects in a lossless way?

I'm familiar with git and subversion.

I know of three options for sharing code between projects:

• Cut and paste - Share code manually. Low coupling. High maintenance.

How to Structure React Unit Tests (with Jest)

Main Template

// A utility method for working with test props (can also be imported)
const createTestProps = (props) => {
  return {
    // common props

React Testing Library Reference

Querying Your React Tree

React Testing Library has methods for several types of queries. There are six query method variants:

• getBy*() - returns the first matching element and throws when an element not found or more than one element found;
• queryBy*() - returns the first matching element but doesn’t throw;
• findBy*() - returns a promise that resolves with a matching element, or rejects when an element not found after a default timeout or more than one element found;
• getAllBy*(), queryAllBy*(), findAllBy*(): same as above but return all found elements, not just the first one.

And the queries are:
