HELP! Functional Programming - Caml Light

Not sure if this is the right place to post this, but here it is anyway: -

Does somebody out there understand the basics? Are there any good practical notes, sites, books etc which can help? I'm really struggling. Be glad of anyone's advice.

What is CAML LIGHT? Sounds like a cigarette :bigyello:

Sorry, I don't know anything about it.

I studied CL at university a few years ago, so if you have any specific questions i'll try and answer them, in the meantime.

I didn't find it too bad. Once you get the hang of the syntax and the way of thinking it's ok.

Hi all, has been a while and have been working hard at the programming. I knew the current situation i'm in would occur and that is why I said a while back that I would need help later on. Later on being now lol.

Anyway, I'm having trouble with lists. This is just one of many many many questions I have, so I will keep it down to the minimum.

I have to state whether a list is true or false, based on the integers in the list.

e.g
[1;2;3;4;5;6;7;8] would come up as TRUE#
[1;2;3;4;5;6;7;8;8;7] would come up as FALSE as this list contains two 7's and two 8's.

I have had a few ideas as to how to do this problem, and one of them is as a follows:-

If I could somehow subtract every value in the TL of the list from the HD, this would mean that if the list were as follows:-

[1;2;3;4;1], then:

1-2 = -1
1-3 = -2
1-4 = -3
1-1= 0

so if the value of the calculation is 0, then FALSE is displayed as a result.

Now I would need to do thsi recursivly, in order to take the hd(tl(tl(tl(tl(x))))

etc.....

So it would subtract every number from a 'HD', and so even if the following list was used, the recursive function would work it out:-

[1;2;3;4;5;6;7;7]

I hope that makes sense. Basically I'm having alot of trouble coding it, but I thinik that the method of solving the problem I have come up with will work.

Can anyone give me some advice and/or help?


Thanks,

Stuart.
