Hello!
It has come to my attention that the tutorial on persistent segment trees here: https://usaco.guide/adv/persistent/#persistent-segment-tree
is pointing to an old link to my slides that got invalidated after a certain update to Google Drive. Here’s a new link to my slides:
https://drive.google.com/file/d/0BwGLW04WRv0ITEZjRWlMSFc2bk0/view?usp=sharing&resourcekey=0-1Zvsu-oMrdNsCuCIU3xGNA
I’ve been getting quite a few emails of people trying to access the slides through the old link, but I didn’t know where they were coming from. Hopefully you can replace the link fast so that they can access the slides properly now.
Best regards,
Oliver-Matis Lill
