StackOverflow contribution

Answered a question on a singly linked list implementation. The question was not very clear since the author is inexperienced. I actually edited my initial post 3 times as the author edited his questions. Ended up deleting my original answer and posting a new one, more concise about the author's code mistakes.

In addition, today I learned (on a high-level) about what is web3, how it works, and thirdweb.
