I thought it will be easy to implement and also a bit of nostalgia.
I was a 2nd/3rd semester CS student at that time when I saw BF code for the first time on a Competitive programming platform named SPOJ. Later, I found it again on a code golfing website.
I thought it would be fun to learn as the language only had 8 commands! I learned it and wrote a tutorial on my native language for my best friend so that we could have some fun together with it :D
