mehdify's Introduction

mehdify

mehdify is a simple test for software engineers.

Difficulty: Medium

Scope

The scope of this test is to assess the candidate's basic knowledge of software engineering principles, their ability to learn, work in a team and follow instructions.

Problem Definition

Implement a function mehdify(x) that takes an integer x and returns the next biggest integer y made up of the same digits. If no bigger number can be found, it should return x.

	mehdify(419) // should return 491
	mehdify(271) // should return 712
	mehdify(542) // should return 542
	mehdify(32142) // should return 32214

You can assume that x is a positive integer.

Instructions

Fork the repository using your own GitHub account.
Give collaborator access to your interviewer(s) (using their email address).
Run npm install on the root directory to install any dependencies.
You may implement your solution in main.js in the /src folder.
- Run the command npm run build to minify, prepare your solution and run any tests. If not all tests are passed then your solution is not complete. If the tests are passed then your solution is returning the correct result; however you will also be assesed on the method.
When you are satisfied, commit and push your changes and create a pull request and assign your interviewer.

Prerequisites

The test does not require any prior knowledge of the problem definition, however basic knowledge of the JavaScript language is required.

Important Notes

Keep your code nice and tidy.
No JavaScript frameworks are required (no jQuery, Angular, React...etc).
Any files outside the /src folder do not need to be modified; including test files.
Use suitable commit messages & gitflow (if necessary)
