A top tree is a data structure based on a binary tree for unrooted dynamic trees that is used mainly for various path-related operations. It allows simple divide-and-conquer algorithms. It has since been augmented to maintain dynamically various properties of a tree such as diameter, center and median. A top tree is defined for an underlying tree and a set of at most two vertices called as (Wikipedia).
What's The Oldest Tree in the World?
Ancient trees are fascinating, but the answer to the question in the title isn't as cut and dried as it might first seem. There are two major contenders for the superlative, and Hank has all the important information on both of them in this episode of SciShow. Which one would you give th
