Homework Help: Disjoint Set Structures

  1. Jun 15, 2008 #1
    The subject is disjoint set structures
    There's following pseudocode for merging sets, by representing every
    set as single rooted tree and merging is like merging trees.

    Code (Text):

    {h[] is array of heights of trees}

         set parent of b is a
      else if(h[a]>h[b])
         set parent of b is a
        set parent of a is b

    It's known that after succesive executions of Merge, the max height of
    tree is log(n).
    The question is if given 4 trees with 20 nodes, what's the maximum height of
    a tree that can be ?
