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 ...)

"Joseph Ring" is a mathematical application of the problem: a group of monkeys in a circle, according to 1,2, ..., n followed by numbers. Then from the first start, the number to the mth, kick it out, start it behind it, count it again, kick it out ... and keep doing so until the end Only one monkey left, the monkey is called the king. Requires programming simulation of this process, enter m, n, output the last king number. The following is a list of three ways to solve this problem with PHP: According to the logic in order to remove recursive algorithm linear table Application Method One: According to the logic of ...

Java Iterator is an interface that provides only the basic rules for iteration, and a foreach loop can be used for any container that implements the Iterable interface.

In addition to the "normal" file, HDFs introduces a number of specific file types (such as Sequencefile, Mapfile, Setfile, Arrayfile, and bloommapfile) that provide richer functionality and typically simplify data processing. Sequencefile provides a persistent data structure for binary key/value pairs. Here, the different instances of the key and value must represent the same Java class, but the size can be different. Similar to other Hadoop files, Sequencefil ...

Java Iterable interface and the Iterator interface. The class that implements the Iterable interface is iterable; the class that implements the Iterator interface is an iterator.
