Just started neetcode blind 150

Just started Neetcode blind 150. This time I’m using java as my tool. Navigating through same challenges and learning more. To be honest, coding on job and coding on coding platform are very different. On job, you use HashMaps and you are mostly done. And there are exceptions when you use DP or Trees. My case, I think I have used mostly all the general data structures and some advanced ones too. But anyways, back to coding and building hand memory again.
