Write a program that takes a sentence as input, where words are separated by spaces, and all the words are in a mix of uppercase and

lowercase letters. The program should convert the sentence to a new string where all words are in lowercase, except for vowels $(\text{'}$a$\text{'},\text{'}$e$\text{'},\text{'}$i$\text{'},\text{'}$o$\text{'},\text{'}$u$\text{'})$ which

should be in uppercase. There should be underscores $(\text{'}\_\text{'})$ between words instead of spaces. Additionally, ensure that the last word in the new string ends

with three exclamation marks $(\text{'}!!!\text{'}).$

For example, if the input is "The quick Brown fox Jumps over the Lazy Dog", the program should output

"thE$\_$qUlck$\_$brOwn$\_$fOx$\_$jUmps$\_$OvEr$\_$thE$\_$IAzy$\_$dOg!!!".

Note: Just use the method, functions that covered in the class. You can not use join function.$(5$ points$)$ Write a program that takes a sentence as input, where words are separated by spaces, and all the words are in a mix of uppercase and lowercase letters.
