Solved LC: 400+

Got unseen question that looked like it could be LC Hard. There were so many ways to solve it. I think that was part of the issue I faced. I kept starting one way and then changing my approach.
It was a mix of DP, Trie, Sliding Window and Regex.

This was my first interview in years, which I new realize was a bad idea.
I kept gettig nervous and digging myself into multiple holes in search of an elegent solution.
Interviewer eventually acknowledged there was no clean solution but he wanted to see thought process and optimizations.

We never got to the follow up questions, so I can only assume I failed.
Haven't heard back in days.

My advice to others is to relax as much as possible. But that's easier said than done, because even I did not take my own advice.

I feel like crap.
