You've explained C in the best way possible, understood every point, learned a lot. Thanks

[@Giovanni-rh1pw]

It's actually crazy how much this guy knows what he's doing. Had to subscribe after the explanation for C

[@x_x3557]

The explanation for C was very very good. The logic for finding kth permutation by travsersing downward in the tree similar to segment trees is sooo beautiful. Keep making such videos!!
