Write a program to do segmentation of words without spaces. Given a string, such as the URL “thelongestlistofthelongeststuffatthelongestdomainnameatlonglast.com,” return a list of component words: [“the,” “longest,” “list,” $\ldots$]. This task is useful for parsing URLs, for spelling correction when words runtogether, and for languages such as Chinese that do not have spaces between words. It can be solved with a unigram or bigram word model and a dynamic programming algorithm similar to the Viterbi algorithm.
