=============
The Challenge - End of Month
=============

Your Boss requires that pay checks must be prepared on the final day of the month. Your goal is figure what the last
day of the month is for any year in the future.

*-->A download is available at ( http://www.kixtart.org/forums/ubbthreads.php?ubb=download&Number=248 )

=============
Specification
=============

Given a date in the format of yyyy/mm/dd or yyyy/mm provide the last day of the month in the format of yyyy/mm/dd.

The function SERIALDATE is included in the scoring engine. If you choose, you can use all or parts of the code from
SERIALDATE in your function, however you are not allowed to directly use/call this function. COM Calls to VB or any
other language are not allowed. Must be a all Kixtart solution.

=============
Inputs and Outputs
=============

The input consists of either a date in the format of yyyy/mm or yyyy/mm/dd. Dates in the past do not need to be
considered.


Output must be in the format of yyyy/mm/dd



=================================================================
Notes
================================================================
- The scoring engine has added code to help diagnose which cases are failing. To see test case results:
 Code:
   kix32 kixgolf_eom $verbose=1 ;shows failing results
   kix32 kixgolf_eom $verbose=2 ;shows all results

- The scoring engine expects your (primary) function to be named a().


=======
Scoring
=======

The solution must pass all tests in order for it's KiXgolf Score to be considered.

When posting KiXtart Golf Scores, please include the KIXGOLF_*.TXT file that is created in the script directory. It contains some basic information about the computer that the script is run on and the resulting scores.

============
Test program
============

Test cases are provided to help screen entries and to provide the Golf Score.
Any script that passes the test cases can be submitted. If you are surprised that your solution passed the test cases, please submit it anyway! That will help me identify bugs in the test program.

================================================================
KiXtart GOLF - How To Play
================================================================

Most importantly, anybody can play, no age restrictions, no penalties, no handicap!

The object in "real" golf is to hit the ball in the hole in the fewest strokes. The object in KiXtart Golf is to get from input (tee) to target (hole) in the fewest keystrokes.

Example: How many positive elements are in array $a?

Array $a could be of structure $a=[1, 2 ,-3, 4, -5, -7, 8, 9]

One approach:
 Code:
for $b=0 to ubound($a)
  if $a[$b]>0
    $c=$c+1
  endif
next

for a score of 45.

Another solution is:
 Code:
DO
  $b=$b+1
  if $a[$b]>0
    $c=$c+1
  endif
UNTIL $b>(UBOUND($a)+1)

for a score of 53.

Better approach: Code sample 1

================================================================
KiXtart GOLF - The Rules
================================================================

1) The goal of KiXtart Golf is to score the lowest strokes.
2) Strokes are all characters in a piece of code except whitespace characters, unless the whitespace character is necessary for the line of code to work. Therefore, carriage returns and line feeds do not count or spaces in between the '=' sign when assigning variables, e.g. '$a = $b' scores 5.
3) Code can be constructed any way you like, as long as it does not generate syntax or other errors when running the script in KiXtart.
4) The final solution MUST pass all test scripts that are part of the KiXtart golf challenge.
7) During the private coding phase, no code is allowed to be posted. Violations result in disqualification of said player.
8) During the public coding phase, code should be posted, reused, and borrowed from other players.
9) The test script contains the official KiXgolf scoring engine
10) Only the person posting a particular score will be recognized for the score, unless the KiXtart Golf Challenge organizer or another delegate posts code on behalf of a player
11) KiXtart Golf (a.k.a KiXgolf) codes must be written inside the KiXgolf UDF collection tags, ';!' and ';!;!'
12) Parameter names of the UDF's can be changed and additional optional parameters can be added.
13) Additional helper UDFs and code can be written as long as they reside inside the ';!' and ';!;!' tags.
14) The use of '$' as a variable is allowed.
15) The UDF layout is up to coder.
16) The UDF is expected to finish in a reasonable time, that is, on modern computers inside 1 hour timeframe.
17) You can submit scores as often as you want.
18) If you reach leading score, you are obligated to post your score immediately so others can try to compete with you.
19) The UDF may only use the KiXtart/KiXforms commands/functions/macros, no other code fragments are allowed.
20) Calls to COM components that are part of a standard default Windows installation are allowed.
21) The use of the KiXforms DLL is also permitted as the KiXforms DLL can now be considered an integral part of KiXtart scripting.
22) Calls to other executables, as long as they are part of a standard default Windows installation are allowed.
23) The UDF should be self-contained (except for any I/O mentioned in the challenge). In particular, you may not do things like fetching extra data from a remote site or file.
24) You may assume ASCII as character set.
25) You may use block comments as the KiXgolf Scoring Engine now supports block comments.
26) You are allowed to only use publicly available versions of KiXtart and KiXforms, private builds or alpha builds are NOT allowed.
27) Your submitted score must include the result print of the KiXgolf test-engine.
28) The SETOPTION() parameters in the KiXgolf script may not be modified and will govern the script behavior. SETOPTION() parameters may change depending on the particular needs of the KiXgolf challenge.
29) Tokenizing the UDF, script, or portions thereof is not allowed.
30) If something is not explicitly denied by the rules, it's allowed.
31) If Confusion arises, arranger of the KiXgolf round has the final say.
32) Additional test cases can be added at any time during the KiXgolf round. The code is expected to pass based on the rules. The test cases may not include tests for all rules and exceptions. Test cases that are added during the public round will not alter the results of the private round.


================================================================
KiXtart GOLF - The Duration of the Competition
================================================================


1) Public Round Only. Ends when the new competion starts. Official count down clock to be provided.

    dim $b
    $ = split($,'/')
    $b = 0,0,3,0,1,0,1,0,0,1,0,1,0
    $a = ''+$[0]+'/'+$[1]+'/'+ (31-$b[$[1]]+($[0] mod 4 = )*(2=$[1]))

well, the previous is of course built after the leap year rules of the julian calendar which are in the mean time obsolete (since 1564 to be precise)

New rules after pope Gregor:

 Quote:

Leap Year Rules

"Concerning the solar year and types of years.
And concerning the leap year." May 29, 1564
There is a leap year every year whose number is perfectly divisible by four - except for years which are both divisible by 100 and not divisible by 400.


Source: http://www.wwu.edu/skywise/leapyear.html

Please consider adding a few testcases:

2400/02=2400/02/29
2100/02=2100/02/28

In the mean time I'll adapt my code to fit the rules ;\)

my first 'gregorian' code for 160 

function a($)
    dim $b
    $ = split($,'/')
    $b = 0,0,3,0,1,0,1,0,0,1,0,1,0
    $a = ''+$[0]+'/'+$[1]+'/'+ (31-$b[$[1]] + (($[0] mod 4=) * (($[0] mod 400=)+($[0] mod 100>))*(2=$[1])))
endfunction
with additional two test cases:

2400/02=2400/02/29
2100/02=2100/02/28

143, look Ma, no DIM

    $a = $[0]+'/'+$[1]+'/'+ (31-substr("030101001010",$[1],1) + ($[0] mod 4=)*(($[0] mod 400=)+($[0] mod 100>))*(2=$[1]))

138 (as there is always a non-numeric char in that string after a number we can omit the length of substr) 


function a($)
    $ = split($,'/')
    $a = $[0]+'/'+$[1]+'/'+ (31-substr(_3_1_1__1_1,$[1]) + ($[0] mod 4=)*(($[0] mod 400=)+($[0] mod 100>))*(2=$[1]))

134 btw: using right vs. substr is in this case equal in score .. 


function a($)
    $ = split($,'/')
    $a = $[0]+'/'+$[1]+'/'+(31-right(_1_1__1_1_3_,$[1])+($[0] mod 4=0 & ($[0] mod 400=0|$[0] mod 100>) & 2=$[1]))

you haven't read the whole thread, didn't you Shane?

add these to the ini and you'll fail 1 of 20 tests ;\)

2400/02=2400/02/29

Thanks for doing the research Jochen.

Everyone please add the two cases to the INI.

2400/02=2400/02/29
2100/02=2100/02/28
