Episode 28 - Sparse Tables and LCA
This week's episode will cover sparse tables and their relationship to the lowest common ancestor problem. I'll be discussing the so called "Euler tour of a tree" which is really just a tree traversal and explain how it helps with this formulation. 00:00 - Welcome 00:39 - Euler Tour of a Tree 04:12 - Tree Linearization 09:48 - LCA Algorithm w ...
