+
+Convert a phrase to its acronym.
+
+Techies love their TLA (Three Letter Acronyms)!
+
+Help generate some jargon by writing a program that converts a long name like Portable Network Graphics to its acronym (PNG).
+
+Punctuation is handled as follows: hyphens are word separators (like whitespace); all other punctuation can be removed from the input.
+
+For example:
+
+| Input                     | Output |
+| ------------------------- | ------ |
+| As Soon As Possible       | ASAP   |
+| Liquid-crystal display    | LCD    |
+| Thank George It's Friday! | TGIF   |
