Thank you ! The prog has 52 bytes on my TI, with one letter for the name, how can it comes in at 55 bytes ? If I use an user-defined list, how can I have the N-th number of the list ?
By the way, whay can't I see the codes in quotes ?

Sorry for my english, I'm french.

If your user-defined list is named, say, ∟A, the N-th element of that list is ∟A(N).

To see them, just press the keys 'Ctrl' and 'A' simultaneously. Alternatively, right click inside the quote box and click "Select All". :D

Thank you, I see that someone did the same code (well, better than me ^^).

As Thornahawk said, use ctrl-A (or just highlight it). The reason we use quotes is to hide the answer so you don't have to see the answer unless you want to.

Oh... I was looking at the wrong program name in my list! You're right, it's 51 bytes.

Welcome, Baruch :biggrin:

Here's another solution that's 42 bytes but only works with positive real numbers (so 0 doesn't work either):

Quote:

Ans->A
{max(Ans
While min(Ans-min(LA
augment(Ans,{max((LA<min(Ans))LA
End


And here's an interesting method that I think might be the smallest if the list is inputted and outputted in LA (works only with positive real numbers again, and takes up 41 bytes):

Quote:

SortD(LA
LAaugment({1},not(not(ΔList(LA->A
SortD(LA
sum(Ans≠0->dim(LA


EDIT: and thanks to Weregoose for the tip that using custom lists like LA is often better than using built-in lists likeL1 because the L doesn't need to be included when storing to custom lists, which helped to make both of these routines a bit smaller

Your second method can be modified to work with all real lists:
Quote:
SortA(LA
augment({0},not(ΔList(LA→B
SortA(LB,LA
sum(not(LB→dim(LA
It is, I think, larger than previously posted methods when you add in the code that puts input and output in Ans instead of LA.
