Need to define how to sort if the counts are the same for two different characters.

Should not be wrong, description contains no info about the order:

[('\n', 9), (')', 35), ('@', 38), ('#', 45), ('_', 45)] should equal [('\n', 9), (')', 35), ('@', 38), ('_', 45), ('#', 45)]

By the way no random tests...
