Determine sentence type

Determine sentence type is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Use this sentence: "hi there, how are you today? I'd like to present to you the washing machine 9001. You have been nominated to win one of these! Just make sure you don't break it"

Task

Search for the last used punctuation in a sentence, and determine its type according to its punctuation

Output one of these letters

"E" (Exclamation!), "Q" (Question?), "S" (Serious.), "N" (Neutral)

Extra

Make your code able to determine multiple sentences

Don't leave any errors!
