This is more like an algorithm, efficiency,storage and design question. I have N arrays and each array may have 0 to N elements. All elements are numbered from 1 to N. I like to find efficient way to do following: Given the element, I like to find top K other elements which makes maximum pair with the given element in any array.

example: 

2 4 5 7 8 10 
1 2 5 6 7 9 
2 6 7 8 9 10 
1 3 5 10 
1 3 4 5 6 8 9 
1 2 4 6 
1 2 4 5 7 10 
1 3 4 6 7 8 9
and if element is '1' and k=3 (Top 3 elements) I will have (6,5,4) as the answer. ie.. (1,6), (1,5) and (1,4) occur most times (incidently 4 times all) as a pair then any other pair, given 1 as one of the element.

For the shorter numbers of arrays I don't have any porblem producing the result. So I am looking an efficient way to handle this for the larger numbers ie.. million arrays. For large arrays, I am ready to reduce the number of elmenets in each array to let's say 20.

Thanks,
artist.
