Welcome to your first code challenge at Red Technologies! Your objective is to create a solution that fulfills the requirements below, which includes passing all of the unit tests that come with this repo.
Given a number, you must coerse it into a palindrome by repeatedly adding its inverse. Your logic should output the following object structure:
interface IOutput {
flips: number; // how many times the number needed to be summed with its inverse
input: number; // the original number
output: number; // the resulting palindrome
}For example, given the following number: 1232, if we add its inverse 1232 + 2321 we get 3553 which is a palindrome. The amount of flips required in this case is 1. Make sure your output is returned in the existing function here: src/codeChallenge/palindromeCoersion.tsx as the unit tests are importing this, expecting a result.
Beware the Lychrel numbers! These are natural numbers that cannot form a palindrome through this type of inverse coersion.
Fork the repo and in the project directory run:
yarn install
yarn start
This project doesn't require a frontend, but feel free to use one and the console if you prefer. Just know that the unit tests don't check for this. When you're ready to test, run:
yarn test
And feel free to take a look at the tests in palindromeCoersion.test.tsx to improve them if you like.
