## tetrisoptimizer
### Objectives
Develop a program that receives only one argument, a path to a text file which will contain a list of [tetrominoes ](https://en.wikipedia.org/wiki/Tetromino ) to assemble them in order to create the smallest square possible.
### Allowed packages
- Only the [standard go ](https://golang.org/pkg/ ) packages are allowed
### Instructions
The program must :
- Compile successfully
- Assemble all of the tetrominoes in order to create the smallest square possible
- Identify each tetromino in the solution by printing them with uppercase latin letters (`A` for the first one, `B` for the second, etc)
- Expect at least one tetromino in the text file
- In case of bad format on the tetrominoes or bad file format it should print `ERROR`
- The project must be written in **Go** .
- The code must respect the [**good practices** ](https://public.01-edu.org/subjects/good-practices/ ).
- It is recommended that the code should present a **test file** .
This project will help you learn about:
- The use of algorithms
- Reading from files
#### Example of a text File
```console
#...
#...
#...
#...
....
....
..##
..##
```
- If it isn't possible to form a complete square, the program should leave spaces between the tetrominoes. For example:
```console
ABB.
ABB.
A...
A...
```
