🔬 TangoMan PHP Lab
===================
#back-end #interview #practice #php #technical-interview #test #training #vanilla
**🔬 TangoMan PHP Lab** is a PHP coding project for practicing common interview questions and coding challenges.
There are various PHP scripts in the root directory that implement different algorithms and solutions to coding problems:
1. 🔄 **Ackermann**
Implements the Ackermann function, which is a classic example of a recursive function that can be used to test compilers and illustrate the concept of recursion.
2. 🔍 **BinarySearch**
Implements binary search to find an element in a sorted array. Binary search is an efficient algorithm for searching sorted data sets and relies on the divide-and-conquer technique.
3. ➕ **Factorial**
Calculates factorials recursively. Factorials are used in combinatorics and provide good examples of recursive functions.
4. 🔢 **Fibonacci**
Generates Fibonacci numbers recursively. The Fibonacci sequence illustrates recursion and has applications in mathematics and nature.
5. 💬 **FizzBuzz**
Prints numbers 1 to 100, but prints "Fizz" for multiples of 3, "Buzz" for multiples of 5, and "FizzBuzz" for multiples of both. This is a common interview screening question.
6. 👋 **HelloWorld**
Prints "Hello world!" - the traditional first program for beginner programmers.
7. ❄️ **MinTemperature**
Finds minimum temperature value from temperature data. Demonstrates algorithms for finding minimum/maximum values.
8. 🔄 **Palindrome**
Checks if a string is a palindrome. Palindromes illustrate recursion and string manipulation.
9. ✔️ **Perfect**
Checks if a number is a perfect number, where the number equals the sum of its divisors. Interesting math and recursion example.
10. 🃏 **Poker**
Evaluates poker hands. Involves evaluating combinations and ranks of cards.
11. 🥇 **PrimeNumbers**
Checks if a number is prime, where a natural number greater than 1 has no positive divisors other than 1 and itself.
12. 🔄 **Rot13**
Encodes/decodes a string using the ROT13 cipher, a simple letter substitution cipher. Basic encryption example.
13. 🔑 **SimpleJWT**
Implements JSON Web Token (JWT) encoding and decoding.
14. 💹 **Stocks**
Return an array holding the names of the top three stocks with the best average performance given two separate arrays containing stocks names and prices.
15. 🔢 **Syracuse**
Implements the Syracuse algorithm/sequence. Interesting recursion and number theory example.
16. 🏗️ **TowerOfHanoi**
Implements the Tower of Hanoi algorithm. A classic algorithm that illustrates recursion and dynamic programming.
17. 🔄 **VonNeumann**
Generates Von Neumann ordinal numbers. Illustrates generating recursive sequences.
✅ Unit Tests
-------------
The `tests` directory in each folder contains `PHPUnit` test cases for testing the implementations of each algorithm.
🚀 Github Actions
-----------------
This project uses Github Actions for continuous integration and testing. The `.github/workflows` directory contains YAML workflow definitions for:
- Linting: Runs `php-cs-fixer` to check code style and quality on every push and pull request.
- Testing: Runs the PHUnit tests.
The workflows help maintain code quality and ensure the tests pass on multiple php versions.
📑 Documentation
----------------
PHPUnit documentation is available here: [https://docs.phpunit.de](https://docs.phpunit.de)
php-cs-fixer documentation is available here: [https://cs.symfony.com/doc/rules/index.html](https://cs.symfony.com/doc/rules/index.html)
