One of his attendants was represented by an oxen, and another was the god of water, and represented by a snake. Vohu Manah and Haurvatat, together with Asha, Kshathra, Armaiti, and Ameretat, were called the Amesha Spentas, who opposed the Daevas. His father, Zurvan, was a deity of space, time, and fate, and his son, Atar, battled a dragon, Azhi Dahaka, that cut Zima in half with a saw.

FTP, name this god, the counterpart of Ahriman, the embodiment of good, and the supreme deity in Zoroastrianism.

Social Science

question:
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.
answer:
Science
