Primary objective: to find a hash function that supports 64-bit integer computation efficiently, so that the efficiency in speed and space is higher than that of other function functions, and 32-bit integer computation in internal

1 overview The time efficiency of the list lookup is O (N), and the log2n,b+ tree is log2n by the binary method, but the time efficiency of searching the hash list is O (1). Design efficient algorithms often need to use the hash list, the constant

The title uses massive data instead of big data ). It seems that big data is still a little virtual. I. Requirements Now we need to design a solution for filtering spam addresses online. Our database already has 1 billion valid email addresses
