Data Comparison Analysis

I have an to do a project that counts the number of comparisons made when searching an array of 1000 elements called list. One for binary search method and a hybrid method of searching. But that is beside the point. For simplicity and neatness I would like to contain everything into one method call. Maybe BinarySearch(list, target) and HybridSearch(list,target). The problem comes when I have to return both the number of comparisons made and the index of the target. I am sure there some ultra easy way to do this that I am not seeing.

Anyone?

Prolog has things called terms or whatever, fuck knows im rusty, long story short,

%% Program %%
lolwat(X) :-
 NumComparisons = 10;
 ResultIndex = 9;
 X = (NumComparisons, ResultIndex).



%% Run time %%
-? lolwat( Awnser ).
Awnser = (10,9).
