Problem Statement

An acronym is a sequence of characters that is used to refer to something with a very long name. An acronym is generated from a long name by capitalizing the first letter of every word in the name and concatenating them together. There are three exceptions: the common words "and", "the", and "of" are ignored when generating the acronym. In this problem, a word is defined as one or more non-space characters preceded by either a space or the beginning of the string and followed by either a space or the end of the string. Write a class VLNString with a method makeAcronym that takes a String longName and returns a String with its acronym generated as described above.

Definition

Class:: VLNString
Method:: makeAcronym
Parameters:: String
Returns:: String
Method signature:: String makeAcronym(String longName)
(be sure your method is public)

Notes

longName may contain leading and trailing spaces, and there may be more than one space between words.
The return value may be an empty string.

Constraints

longName will contain between 1 and 50 characters, inclusive.
longName will contain only lowercase English letters ('a' to 'z') and space characters.

Examples

```
"dance dance revolution"
```
```
Returns: "DDR"
