This course provides the best approach to learn Rust, starting from the basics and advancing to complex topics. It is an introduction to Rust for beginners aspiring to become skilled Rust developers.

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 course, you'll learn Rust by actively engaging in coding. You’ll start with a simple "Hello world" program and cover 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.
By the end of this course, you'll have a solid foundation in Rust programming and be well-prepared to take on more advanced concepts, making it ideal for Rust beginners looking to become proficient Rust developers.

Rust Programming Language

fn test(my_vec: &mut Vec<u32>)-> &mut Vec<u32>{
   let middle = (my_vec.len())/2;
   my_vec.pop(); 
   my_vec.remove(middle - 1);
   let mut sum : u32 = 0;
   for v in my_vec.iter()
   {
      sum = sum + v;
   }
   my_vec.push(sum);
   my_vec
}
fn main(){
    let mut v1 = vec![1, 5, 7, 9];
    println!("Original Vector: {:?}", v1);
    println!("Updated Vector: {:?}", test(&mut v1));
    let mut v2 = vec![1, 2, 3, 1, 2, 6];
    println!("Original Vector: {:?}", v2);
    println!("Updated Vector: {:?}", test(&mut v2));
}

fn test(my_vec: &mut Vec<i32>){
   my_vec.remove(2); // remove the value at position 2 => 1 2 4 5
   my_vec.pop(); // pop the last value => // 1 2 4 
   my_vec.push(6); // push a value at the end => // 1 2 4 6
   my_vec.push(9); // push a value at the end => // 1 2 4  9
   //print vector
   print!("{}{}{}{}{}", my_vec[0], my_vec[1], my_vec[2], my_vec[3], my_vec[4]);
}

## Explanation

A function `test` is declared with `my_vec` of type `u32` passed to it as a parameter.
* On **line 3**, a number is removed from the last index using `pop` function,   so the number `9` (the last element) gets removed.
* On **line 4**, a number is removed at position 1 using the `remove` function,   so the number `5` (the middle element) gets removed.

* On **line 5**, a mutable variable `sum` is initialized to 0.

* On **line 6-9**, a variable `sum` stores the summation of elements of the vector by iterating using a `for` loop over the vector using `my_vec.iter()` 

* On **line 10**, a `sum` is added to the last index of `my_vec` using `push` function.

* On **line 11**, `myvec` is returned.
