    Congrats bhaiya for air 1 in Google kickstart

    The contests these days are more observation/greedy based then previous contests (i.e. the 500/600 series, where there were many DP and graph problems at C/D). I started recently and reached expert without knowing anything in DP/Graphs, so I think beginners should focus more on problem solving in observation/greedy problems. Great video nonetheless!

    Something that stands out in this video is that every topic has a different set of resources which is really helpful because each topic is covered best by a specific resource/site and no individual site covers *all* resources perfectly. This is really difficult to find for a beginner.
    Appreciate it!

    Even u won't agree more, to solve A, B and C in div2 rounds u need just few skills :
    Number theory
    Greedy
    Quick observations for constructive problems
    Quick brute force (to simulate and catch observations)

Will you make a video on which software you use to record video? In other videos I saw you using some combination on which we, the viewer, see you, your keyboard and your screen. How do you do that? Consider making a video on that? Take love from Bangladesh.

      Depends on how much you can comprehend. If you feel like you are not understanding anything after the 2nd module, that might just mean you need to practice more problems based on topics covered till module 2 and return back to the 3rd one when your level has improved. There is no need to do these topics exhaustively. You can cover how much you are able to understand.
