Review Comment:
@itholic Could you restrict the number of columns by sorting the list (to
have stable output) and return top 3 columns. Or be more smarter and output 3
columns that starts from the same char as the unresolved column, and if it is
empty, just print the first 3 columns of the sorted list.
