Write a function cyclic_toptail() which takes a single argument sentence in the form of a non-empty string, and returns True if ll words in sentence start with the final letter of the word that precedes them (including the first letter of the first word being the same as the last letter of the last word), and False otherwise. You may assume that sentence is all lowercase, does not contain any punctuation, and that words are separated by spaces. For example, in the case of sentence being "giraffes sing", the function should return True, as: (a) the first word ("giraffes") ends in the same letter as the first letter of the second word ("sing"), i.e. s; and (b) the first letter of the first word is the same as the last letter of the last word, e.g. g. In the case of "giraffes sulk", on the other hand, the function should return False, as the first letter of the first word (g) is not the same as the last letter of the last word (k). Example calls to the function are: >>» cyclic_toptail("giraffes sing") True >>> cyclic_toptail("giraffes sulk") False >>> cyclic_toptail("seals slurping green negronis") True >>> cyclic_toptail("abracadabra") True >>> cyclic_toptail("alakazam") False >>> cyclic_toptail("the cat sat on the mat") False
