Hi,
I have two elements, say A and B and their positions in a three
dimensional list. Eg {1,3} means that position of A is 1 , position ob
is 3 and a list is given {A,_,B}. {3,2} corresponds to {_,B,A}, {3,3}
corresponds to {_,_,{A,B}}.
How can I code it in Mathematica using any number of elements and a
list of any length>0?
Thx,
Arek
