Problem Statement for "CompleteDate"

Problem Statement

You are designing a word processor which automatically expands a date entered in shorthand format (e.g. "8/28/03") into its full format (e.g. "August 28th, 2003"). The full format is explained below.

Create a class CompleteDate containing a method expand that takes a String date, which is in shorthand format, and returns the expanded full format.

The shorthand format of date shall be as follows:

"M/D/Y"

1) M, and D do not have leading zeros

2) M is an integer between 1 and 12 inclusive representing the month

3) D is an integer between 1 and 31 inclusive representing the day of the month

4) Y is an integer between 0 and 99 inclusive and will always be written as 2 digits (i.e. "00","94","09" are all valid Y values)

Month 1 corresponds to "January", month 2 corresponds to "February", and so forth.

The expanded format is the month's name, followed by a single space, followed by the expanded form of the day (no leading zeros), followed by a single comma, followed by a single space, followed by the four digit year. Month names are: "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", and "December". The day of the month has 2 letters added to it, depending on the ending. For days 1, 21, and 31, add "st". For days 2 and 22, add "nd". For days 3 and 23, add "rd". For all other days, add "th". The years range from 1970-2069, so notice that the year "70" is actually 99 years before the year "69". See examples for more clarification.

TopCoder will ensure that the date is valid. The number of days possible depends on the month. Days start at 1 and go to 30 for April, June, September, and November. They start at 1 and go to 31 for January, March, May, July, August, October, and December. Finally, they start at 1 and go to 28 in February, except in a year divisible by 4, in which case they go up to 29.
