This module provides the best approach to learn Rust, starting from the basics to advance topics. It is an introduction to Rust, specifically for beginners aspiring to become skilled Rust developers.

Become a Rust Web Developer

The word is out: developers love Rust. It's rapidly becoming a top choice for systems and embedded programmers, and the demand for Rust developers is rising. Known for its performance, reliability, and productivity—especially compared to C++—Rust is a powerful language to master. If you're a systems developer, it's a fantastic next step.
In this module, you'll learn Rust by actively engaging in coding. It starts with a simple "Hello world" program and covers essential concepts like arrays, strings, vectors, enums, structures, traits, generics, functions, and logic. You'll also dive into advanced topics such as lifetime and memory management.

## Problem Statement
Write a function `test_divisibility_by_3_4` which will check whether a given integer number is `divisible by 3 or 4`. 

* If the number is divisible by both return 0
* If the number is divisible by 3 only return 1
* If the number is divisible by 4 only return 2
* If the number is not divisible by both, return -1
### Input
```
    integer
```
### Output
The output can be any of the following:
```
    0 , 1 , 2 ,-1
```

### Sample Input 
```
    12 , 9 , 16 , 19
```
### Sample Output
```
    0 , 1 , 2 , -1
```

## Coding Exercise

Write your code below. It is recommended​ that you try solving the exercise yourself before viewing the solution.

> **Note:** There is a `test_divisibility_by_3_4` function given in the code for testing purposes. Do not modify it.

Good luck!🤞
