BASH from beginner to advanced: Solutions to Hackerrank Challenges - Episode 8: Looping with Numbers

Welcome to this in-depth series of videos where we will be providing solutions and explanations for various BASH challenges from Hackerrank. In this video, we will be tackling the "Looping with Numbers" challenge, which can be found at this link: www.hackerrank...
Our goal in this series is to document my thought process and solutions, and to focus on concepts and ideas rather than details. I will also be highlighting the differences between BASH and popular programming languages like Python and JavaScript.
BASH is a powerful command-line interface for interacting with an operating system. It's a shell, and the most popular one. It can be used directly in the terminal or in scripts, which are text files containing a series of instructions. BASH is particularly useful for tasks such as text processing, file operations, connecting multiple programs, and system maintenance. It is also portable, working by default on many platforms.
A for loop in bash is used to iterate over a sequence of items, such as the elements of an array or the lines of a file. The basic syntax is as follows:
for variable in sequence; do
commands
done
The sequence can be a list of items, such as numbers or strings, separated by spaces. The commands are the commands that will be executed for each item in the sequence. The variable is a placeholder that will take on the value of each item in the sequence during each iteration of the loop.
For example, the following loop iterates over the numbers 1 to 5 and prints each number:
for i in 1 2 3 4 5; do
echo $i
done
The output will be:
1
2
3
4
5
