Which of the following lists matches with [X|[X,Y|[Z]]] ?
[a,[a],b|[c]]
[[a,a],[b],[c]]
None of the lists match [a,a|[b,c]]
[a,[a,b|[c]]]
Which values for each variable will make the following two lists match: [a,X,c,Y|S] and [Y,[c,X],a]
The lists do not match because they contain a different number of elements
X = [c,c], Y = a, S = [ ]
X = c, Y = a, S = [ ]
The lists do not match because they contain different elements at the same position X = [c], Y = a, S = [ ]
