Is this splay tree incorrect in this UC Berkeley lecture video?
https://youtu.be/G5QIXywcJlY?t=31m47s
At 31:47, I believe he performs a double right rotation with 5 being the grandparent, and 4 being the parent, and 1 being the child. After the double right rotation, he has 4 as the right child of 5.

Priority queue with O(1) Get-Min, Delete-Min and Merge operations
I'm wondering if there is a way to construct a priority queue structure that supports constant-time get-min, delete-min, and merge operations. I don't care about the time complexity of insertions and it doesn't have to support the decrease-key…

Can not figure out how splaying works
I can not understand how splaying works.
The part that I can not follow is how we know if a: i) zig ii) zig-zag or iii) zig-zig must be done.
If I understand correctly this has to do with the current node in the path.
If it is the root's child then…
