... • We assume that the tree is given as a set of adjacency lists for the nodes. The adjacency list L[v] for v is given in an array. • Consider a node v and a node ui adjacent to v. • We need: – The successor < v, u(i + 1) mod d > for < ui, v >.

... This doesn’t help us in the worst case, because if our last merge happens to deal with sets of roughly equal size, we will need Θ(n) time to do it. But what we really care about is the total time to perform a series of operations. Determining this total time is our first example of amortized analysi ...
