## Task

Your task is to replace the blanks `___` with the correct data types for each of the variables. For the `temperature` variable use the **integer** data type which takes up the **least** memory provided that the number fits in its range.

Dive into Scala programming with this introductory course, covering the essentials from syntax to advanced data types. Discover Scala's benefits, master variables, control structures, arrays, and strings through practical examples and challenges.

First, we'll explore Scala's advantages, how the language works, its syntax, writing basic programs, and the use of comments.

Like every other programming language, Scala is based upon variables and data types, so let's learn about Scala's basic data types, variable type inference, mutable vs immutable types, arithmetic, assignment operators, and character specifics.

Now it's time to master the use of conditional statements and loops which will allow us to make our programs flexible and avoid code repetition. 

Arrays are essential for storing multiple values and manipulate them conveniently. Without further ado, let's learn how to create arrays, process them and apply these concepts in practice.

Finally, we'll learn how to deal with strings in Scala efficiently by discovering the nature of strings, effective iteration techniques, key string methods, and their application.
