================================================
The Challenge - Happy Numbers
================================================


A happy number is defined by the following process: Starting with any positive integer, replace the number by the sum of the squares of its digits,
and repeat the process until the number either equals 1 (where it will stay), or it loops endlessly in a cycle that does not include 1.
Those numbers for which this process ends in 1 are happy numbers, while those that do not end in 1 are unhappy numbers (or sad numbers)

For example, 19 is happy, as the associated sequence is:

1 + 9 = 82
8 + 2 = 68
6 + 8 = 100
1 + 0 + 0 = 1

The rules:

Input will be a positive number between 1 and 200 (Vartype is string).
The challenge is to write the shortest code to return either 'happy' or 'sad' based on the input.

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


Example Input
19

Output
happy

Example Input
4

Output
sad

================================================================
Notes
================================================================

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

I thought we had a Happy Numbers in the past...

I haven't looked close enough to see if the challenge is the same.

What now?

Well,

as the challenge is exactly the same and only differs in the output, I'll just close this challenge as there are working solutions posted with a very low score already.

Sorry to spoil the fun everyone.

Let me know what your plans are.

I have a tourney close to ready. I could work on it and put it up today if necessary.

Okay. In progress. I may release it earlier than I would normally, and then later update the INI with more tests.
