max () returns the maximum value. Syntax max (x, y) Parameter Description x Required. A few. y necessary. A few. Description max () Returns the value with the highest value in the argument. If there is only one parameter and an array, max () returns the largest value in the array. If the first argument is an integer, string, or floating point number, at least two arguments are required and max () returns the largest of these values. You can compare an unlimited number of values. echo max (1,3,5,6,7); & ...

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 ...
Describes the use of unmanaged Win32apis encryption to decrypt data before. NET is a very painful thing to do. For the purpose of this cryptographic decryption. NET is configured with a set of classes (and namespaces). Now you have a lot of classes that can protect your data using each of these different algorithms. There are 3 types of encryption methods defined within the. NET Crypttography namespaces. They are asymmetricalgorithm,symmetricalgorithm and HashAlgorithm. All the ...
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 ...)

Hadoop RPC communication is different from other systems RPC communication, the author for the use of Hadoop features, specifically designed a set of RPC framework, the framework of personal feeling is still a little complicated. So I'm going to split into client-side and Server service-side 2 modules for analysis. If you have a good understanding of RPC's entire process, you must be able to understand it very quickly for Hadoop RPC. OK, let's cut to the chase. The related code for the RPC of Hadoop is ORG.APAC ...
