Write a program that converts a sentence input by the user into pig latin. You can assume that the sentence contains no punctuation. The rules for pig latin are as follows: For words that begin with consonants, move the leading consonant to the end of the word and add "ay". Thus, "ball" becomes "allbay"; "button" becomes "uttonbay"; and so forth. For words that begin with vowels, add "way" to the end. Thus "all" becomes "allway"; "one" becomes "oneway"; and so forth.
