This is me Rachit Jain.
I had made a playlist for the previous August Challenge, which you can see HERE.
I was busy with office work recently, hence the delay for the video editorials for the September Long Challenge 2017(and also my poor performance ).
Anyways, my interest and love for the 6th problem(which I missed by 50 points because of a single test case.) which is Weasel Does Xor on Tree motivated me to release the video today itself, highlighting -
- How to approach problems when you have no idea?
- How to go further into depths, analyzing the problem in hand when you are stuck? Losing hope doesn’t helps. Wait. Relax. Go deep.
- The beautiful pattern of the matrix <3 Math really amazes me and I love it!
I have launched the 1st video where I explain the solution journey.
Check it out here:
Part 1: https://youtu.be/FhC6A4mvXUw(Weasel does XOR on Tree - Part 1)
Part 2: https://youtu.be/HIVZ9HVSIb0(Weasel does XOR on Tree - Part 2)
I will probably release video for 5th problem: Fill the Matrix tomorrow.
UPDATE: New Video is out.
