Smooth Sentences

Carlos is a huge fan of something he calls smooth sentences.

A smooth sentence is one where the last letter of each word is identical to the first letter the following word (and not case sensitive, so "A" would be the same as "a").

The following would be a smooth sentence "Carlos swam masterfully" because "Carlos" ends with an "s" and swam begins with an "s" and swam ends with an "m" and masterfully begins with an "m".

Create a function that determines whether the input sentence is a smooth sentence, returning a boolean value True if it is, False if it is not.

Examples

is_smooth("Marta appreciated deep perpendicular right trapezoids") ➞ True

is_smooth("Someone is outside the doorway") ➞ False

is_smooth("She eats super righteously") ➞ True

Notes

• The last and first letters are case insensitive.
• There will be no punctuation in each sentence.
