Amortized Conc-Tree Appends

This lecture covers the implementation of constant time appends in Conc-Trees, introducing a new Append node with different semantics to achieve O(1) appends with low constant factors. It also explores counting in a binary number system and the binary number representation, discussing the implementation of an immutable data structure with O(1) appends and O(log n) concatenation, and the possibility of a more efficient, mutable data Conc-tree variant.
