Retro - Did pretty okay - fastest finish in awhile! Silly mistake on Q3, need to be more patient, but the testing was a bit slow and it frustrated me a bit. 78th, not a bad way to start off the year!

Hello Larry,
I really appreciate your videos because you explain the real mindset and thought process during the contests.
I would really love to learn more about how did you come to this point, one point which I can clearly see is consistency.
Since one point of making these videos could be as a video portfolio rather than having a website to show your problem solving skills.
Other could be to give an exposure to others and let them learn. I am not sure whats the real reason for you though.
I would really appreciate if you could make a video about how to be the point where you are at and about yourself.

Today we have a rat race in becoming software engineers
By bootcamps, self taught, interview prep courses.

But doing good at competitions is a different than those.
I would like to learn how to be like you in this, if you are planning to make a video on that.
Thanks for the videos. I appreciate your efforts.

Hi Larry! Thanks for this content really enjoy watching them. I am wondering how you just knew the approach to the last problem? I really got stuck on that one even if I sensed it would be dynamic programming, but it was just hard for me to visualize the subproblems. Do you have tips on better pattern recognition on DP problems? Thanks !
