Ep.1: Depth-First Search - LeetCode Problems That Got Me Hired

In this video, I break down depth-first search, which is a generic but extremely versatile pattern that you NEED to be comfortable with in a software engineering interview. I primarily talk about 3 problems: Letter Combinations of a Phone Number, Number of Islands, and N-Queens.

I'm starting this series where I dissect crucial coding interview patterns and discuss LeetCode problems I've done (while prepping for my own interviews) that I think are particularly essential. My goal is not to make tutorials on specific problems, but to highlight key takeaways and expose underlying algorithmic patterns.

😬 About Me 😬
I'm a software engineer at Google, where I previously interned for two summers. I recently graduated from college as a computer science major. Now I sit in my room and talk to my camera to compensate for the fact that I have no social life.
