# Linian Number Analyzer Code Challenge
We have to write a program that prints all the numbers from 1 to 100. However, for
multiples of 3, instead of the number, print "Linio". For multiples of 5 print
"IT". For numbers which are multiples of both 3 and 5, print "Linianos".
But here's the catch: you can use only one `if`. No multiple branches, ternary
operators or `else`.
## Requirements
- 1 if
- You can't use `else`, `else if` or ternary
- Unit tests
- Feel free to apply your SOLID knowledge
- You can write the challenge in any language you want. Here at Linio we are big fans of PHP, Kotlin and TypeScript
# Solution
The solution purpose is to implement the described rules above with pre-defined analyzers.
This way we can concentrate each analysis in a self-contained class with a common contract with other analyzers.
This contract is made to receive an integer and return a simple string with the analysis result.
In case the analyzer is not the right one for the number, the Analyzer will return `null` and the AnalysisManager will try to run the next Analyzers until he finds one that returns the analysis result. For that reason we will have a Fallback analyzer called DecimalFallbackAnalyzer.
## Getting started
Before running the analyzer, you will need to install the project dependencies with `composer install`.
### Running the Analyzer
By default the analyzer will run in the range from 1 to 100, you can run it with this simple command:
```
bin/linian-number-analyzer
```
If you receive the permission error, try adding execution permission for this binary file:
```
chmod +x bin/linian-number-analyzer
```
## Running the tests
To run the test cases within this project just execute:
```
vendor/bin/phpunit tests/AnalyzersTests.php
```
