*An Update on problem E:*
My solution that I showed in the video was hacked after the contest. The problem was that, it was using O(n^2) memory, which was just greater than the memory limit, and, after optimising a little on memory, the extra log(n) factor of the map was making the solution O(n^2logn), which was giving TLE.
So, I have used a vector instead of a map to store those values, and that too in an optimised way(not till n for every node, but till only where it's needed), so it is accepted now. *I have attached the accepted solution in the description.*
