It says long. So I presume you don't have enough memory in RAM for doing this... Care to elaborate?

It didn't say that there will be ALL long numbers in file. Need to be more clear about possible number of elements and amount of memory. Anyways,if bit array wouldn't fit into memory as well, we may use trie with string representation of those numbers, which I presume should take a lot less memory, since a lot of numbers would have long common prefixes.

use hash to divide the whole large file into many small file,make sure that the same number are in the same small file,then handle the small file independently...
