Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	allen, it's a positive increment. what I mean, if you start 1, either it counts 4 billion loops to reach zero or it does loop infinetly. but starting from 1 can't be right away 0, as my math says 1=0 is false. thus, a bug. _________________________ ! download KiXnet

Allen Allen KiX Supporter Registered: 2003-04-19 Posts: 4549 Loc: USA	Your understanding of math/programming is well beyond mine... no doubt about it. I guess I could see what you mean about infinity, but I guess I would never see how it is a positive increment. 0 is less than 1 (I think anyway )

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	well, positive increment it is if I don't specify negative step, right? so, it doesn't matter what is the final number, it will count positively. now, you wonder why I expect it to come back to zero at some point? that's because once it reaches 2 147 483 647, it can't add no more numbers, it's the limit. thus, adding one more to that will result in -2 147 483 647 and -2 147 483 646 after that, until it would reach zero. anyway, like said, it doesn't matter what is the X in "to X", kix should always keep on incrementing until it hits that value. and as 0 is smaller than the starting number of 1, it should just keep on looping. approx. 4 294 967 294 times to be exact. _________________________ ! download KiXnet

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Interesting Code Dale, there is no loop!??! Will have to have a look on it... or maybe a stare edit: I don't get it ... there is no loop but if I comment if $ I get a stack overflow error edit some more: Oh, recursively calling itself, didn't see that Edited by Jochen (2007-07-24 08:50 AM) Edit Reason: Now I see _________________________

acmp acmp Getting the hang of it Registered: 2004-07-02 Posts: 69 Loc: Bingham, Nottinghamshire, Engl...	Here's my 81 Code: Function a($b) Dim $, $w For $ = 1 to 255 $w=Asc(SubStr($b,$))-64 if $w>0 $a=$a+$w*$ EndFunction I've really got to get my head around these recursive function calls to see if it can be improved. You chaps have some mean tricks up your sleeves. Edited by acmp (2007-07-24 09:47 AM) Edit Reason: oops, mis stated $w>0 _________________________ Every day is a school day

Richard H. Richard H. Administrator Registered: 2000-01-24 Posts: 4946 Loc: Leatherhead, Surrey, UK	Benny's code reduced to 78 Hey Jooel - no DIM Code: Function a($) if $ $a=asc(right($,1))-64 $a=a(left($,~))+len($)$a($a>) EndFunction

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Jens, am I allowed to introduce a second required parameter to the udf and change the test script to pass an additional value ? If yes, there would be a shiny 71 score edit: I think not as the rules clearly state that optional parameters are allowed, Jens? _________________________

acmp acmp Getting the hang of it Registered: 2004-07-02 Posts: 69 Loc: Bingham, Nottinghamshire, Engl...	Jochen, Rule 12: 12) Parameter names of the UDF's can be changed and additional optional parameters can be added. Go for it. _________________________ Every day is a school day

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Well optional is the culprit here. optional scores 8 so the improvement would be negative (84). If required would be possible.... _________________________

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Ok, reworked my own code for a nice 78 score Code: function a($) dim $i for $i = 1 to 255 $a = $a + $i * (asc($)-64) * ($>!) $ = right($,~) endfunction Running Test 1...Done Running Test 2...Done Running Test 3...Done Running Test 4...Done Running Test 5...Done Running Test 6...Done Your solution passed all tests KiXtart KiXtart Version = 4.53 KiXGolf Script = KIXGOL~1.KIX Computer OS = Windows 2000 Professional CPU = Intel(R) Pentium(R) 4 CPU 2.80GHz Speed = 2793 MHz Memory = 504 MB KiXGolf Scoring Engine Scoring Engine = 3.3 KiXtart Golf Score Tournament = Quicksum Processing Start = 2007/07/24 10:39:21.640 Processing End = 2007/07/24 10:39:21.656 Duration = 0000/00/00 00:00:00.016 KiXGolf Score = 78 Thank you for participating in KiXtart Golf! _________________________

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	Yo, the ($>!) is just validating if the character $ starts with has a higher 'value' than ! (Not every string needs quotes). So if $ starts with a space character the expression results in 0 (! = ascii 33, space = 32), and if it starts with a Letter it results in 1 This feature can be utilized for eg. sorting functions... _________________________

Jochen Jochen KiX Supporter Registered: 2000-03-17 Posts: 6380 Loc: Stuttgart, Germany	This feels a bit like cheating, but hey, it's a 77 Code: function a($) dim $i for $i = 1 to 99 $a = $a + $i * (asc($)-64) * ($>!) $ = right($,~) endfunction Running Test 1...Done Running Test 2...Done Running Test 3...Done Running Test 4...Done Running Test 5...Done Running Test 6...Done Your solution passed all tests KiXtart KiXtart Version = 4.53 KiXGolf Script = KIXGOL~1.KIX Computer OS = Windows 2000 Professional CPU = Intel(R) Pentium(R) 4 CPU 2.80GHz Speed = 2793 MHz Memory = 504 MB KiXGolf Scoring Engine Scoring Engine = 3.3 KiXtart Golf Score Tournament = Quicksum Processing Start = 2007/07/24 10:52:16.140 Processing End = 2007/07/24 10:52:16.156 Duration = 0000/00/00 00:00:00.016 KiXGolf Score = 77 Thank you for participating in KiXtart Golf! _________________________

acmp acmp Getting the hang of it Registered: 2004-07-02 Posts: 69 Loc: Bingham, Nottinghamshire, Engl...	Thanks for explaining, I substituted the ! for 0 and found it still worked so I was assuming it was something like that. Code: for $i = 1 to 255 glad I could help $;\)$ _________________________ Every day is a school day
