▬ About Algorithms Simplified ▬▬▬▬▬▬

I am a software engineer and computer science student who specializes in mathematics, logic, and algorithms. When I was a 2nd-year university student, despite having only *started* programming for 6 months before my first interview, I received multiple FAANG + other software engineering offers following my interview rounds due to my strength in algorithms. I’d like to bring both my passion for mathematical logic and experience interviewing for software engineering roles to you, the viewers, so that you may be better prepared for your next coding interview.

On this channel, I walk through Leetcode interview questions in excruciating detail, so that you can really understand, not memorize. If you enjoy these walkthroughs and explanations, please consider subscribing, as these videos take a lot of work.
