Learn the syntax, data types, and operations essential for programming in Scala

Become a Scala Developer

In this module, we will learn Scala from the ground up. This module aims to teach us how to write basic programs, assuming we have no prior knowledge of the language. We will start with a brief introduction to Scala to understand its functionality and applications. We will then move discuss the key features and functions of the language (data types, functions, classes, etc.) in detail. In the end, we will have all the basic knowledge of how to program in Scala.

## Task

In this challenge, you were provided a list. Your task was to append an element to the list having the same value as the first element of the same list. 

## Solution

The task required you to use the append `List` operator `:+` which appends an element to the end of a list. The operator has two operands:

* The first operand is the list to which you wish to append an element.
* The second operator is the element you wish to append to the end of a list. 

In our case, the first operand would be `list` and the second operand would be `list(0)`. `list(0)` is accessing the first element of `list`.


You can find the complete solution below:
