This works, but only if the data is in the form
[x =: 3 2 1 4 # 4 2 1 3
4 4 4 2 2 1 3 3 3 3
NB. and not scrambled, eg
y =: 3 1 4 3 3 4 3 2 4 2
;@((<@[EMAIL PROTECTED])/.~)x NB. developed from your solution
0 1 2 0 1 0 0 1 2 3
Is that what you need or do you also need a
result for scrambled x?

Hi,
I have a problem to create a verb. I think it is quite easy, but
unfortunately I can not.
My Input (example) : 4 4 4 2 2 1 3 3 3 3
As output, I would : 0 1 2 0 1 0 0 1 2 3
I would like a verb which counts the iteration number for same element.
It is equivalent to : (i. 3) , ( i. 2) , ( i. 1) , ( i. 4)
I can do the line above because of the parenthesis.
I can only get the vector : 3 2 1 4 easily with #/.~, but that is all.
Any idea ?
Thank you. Bye.
Damien.
