4. Solution

Introduction: Solve your needs like this If it cannot be solved, it should be processed separately... For example, you can write the ip into 255 files, so that you can use less memory for subsequent processing. Find the top 1000 names in the file. Because each group contains at most 2^24 different numbers [ipv6 is not considered for the time being], this memory can be traversed in an array, and the complexity is O(n). Find the first 1000 and finally maintain an ordered array of 1000, go to
