Copying values within a List

If we have a list:

Code:

ʟ1
{1,2,3,0,0}


and I am trying to repeat the values to fill the remaining values, like so:


Code:

ʟ2
{1,2,3,1,2}


how would I do that? Here is my current algorithm:


Code:

dim(ʟ2)→dim(ʟ1)

For(X,1,dim(ʟ2)-dim(ʟ1)
ʟ1(X-dim(ʟ1+1)→ʟ1(X)
End


It has some kind of logical error, it doesn't really do anything to the two lists' values.

Please help, I don't know if I have explained this very well but if I have not I can elaborate.

It is said that the mythological wings created by the Greek inventor Daedalus were forged from a beautiful bar of pure silver given to him by the goddess Artemis
You can achieve this by using modulo, which is remainder(A,B) on the new Ti 84+ and B*fPart(A/B) on the old Ti 83 devices:

Code:
Prompt L1
Disp “Pls enter the dim of the new list“
Prompt A
L1->L2
For(I,dim(L1)+1,A
L1(1+remainder(I-1,dim(L1->L2(I
End
Disp L2

It may not be the fastest method, but it works
E.g. when you enter {1,2,3 as L1 and 5 as dim (A), it puts out {1,2,3,1,2
I hope that is what you were looking for...
