Input: Consider Input: A maximum independent set for this data structure can be found in linear time by adding alternating levels. In this structure, any two vertices or nodes must be connected by a single simple path, and thus it is connected and acyclic. By using (*) union-find with disjoint sets, one type of this structure containing all the vertices of a connected graph can be constructed. One variety of this data structure can be used to easily implement a binary search. This structure also comes in red-black and self-balancing-binary varieties. For 10 points, identify this data structure from computer science, a hierarchical graph in which "leaf" nodes ultimately flow from a "root" node.

Output: Science

The speaker of this poem realizes that "now it seems to me the beautiful uncut hair of graves" in pondering a child's inquiry "What is the grass" This poem's speaker asks "Do I contradict myself," admits "Very well then I contradict myself," and explains "(I am large, I contain multitudes.)"
