Here I created and completed my first codecrafter challenge: "Build Your Own Shell" Challenge.

In this challenge, I built my own POSIX compliant shell that's capable of interpreting shell commands, running external programs and builtin commands like cd, pwd, echo and more. Along the way, I'll learn about shell command parsing, REPLs, builtin commands, and more.

Note: If you're viewing this repo on GitHub, head over to codecrafters.io to try the challenge.
