For example, want a random number between 5 and 15 (including 5 and 15), with Rand (5, 15). Let me take a look at a specific example, we do a basic function call, do not set the specific parameters, we get the random number ...

1. Given a, b two files, each store 5 billion URLs, each URL accounted for 64 bytes, memory limit is 4G, let you find a, b file common URL? Scenario 1: The size of each file can be estimated to be 50gx64=320g, far larger than the memory limit of 4G. So it is not possible to fully load it into memory processing. 　　Consider adopting a divide-and-conquer approach. s traverses file A, asks for each URL, and then stores the URL to 1000 small files (recorded) based on the values obtained. This ...

Algorithm one: Fast sorting algorithm is a sort algorithm developed by Donny Holl. In average, sort n items to be 0 (n log n) times compared. In the worst-case scenario, 0 (N2) comparisons are required, but this is not a common situation. 　　In fact, fast sorting is typically faster than the other 0 (n log n) algorithms because its internal loops (inner Loop) can be implemented efficiently on most architectures. Quick sort using divide-and-conquer method (http://www ...)
