In computer science, an x-fast trie is a data structure for storing integers from a bounded domain. It supports exact and predecessor or successor queries in time O(log log M), using O(n log M) space, where n is the number of stored values and M is the maximum value in the domain. The structure was proposed by Dan Willard in 1982, along with the more complicated y-fast trie, as a way to improve the space usage of van Emde Boas trees, while retaining the O(log log M) query time.

Trigonometry - Working with linear and angular speed
When working with wheels its important to recognize that there is a connection between linear and angular speed. This video will show a few example on using the formula v = rw for finding either linear speed or angular speed. Near the end we also cover how to covert unit which is useful
