Suppose that we want to change the IP address of www. uga. edu from 128.192.225.20 to 128.192.224.40. We change this mapping in the DNS authoritative name server. Once this mapping is changed in the authoritative name server, will all future references in the Internet to www. uga. edu then be sent to 128.192.224.40?

Implement a document scanning function wordcountengine, which receives a string document and returns a list of all unique words in it and their number of occurrences, sorted by the number of occurrences in a descending order. if two or more words have the same count, they should be sorted according to their order in the original sentence. assume that all letters are in english alphabet. you function should be case-insensitive, so for instance, the words “perfect” and “perfect” should be considered the same word.
