# Instructions | ||
|
||
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 | |
