Search engine have to record all of the query string. Now i have a
search engine log which contains 10 milllion query strings, but almost
of them are repeated, not more than 3 million of them are non-
repeated.
My task is to pick the top 10 most popular query string, memory < 1G,
the length of the query string is no more than 255.
The faster, the better.
the principal solutions, algorithm and data structure.
Thank you.
