The bucket sort (Bucket sort) or the so-called box sort is a sort algorithm that works by splitting the array into a finite number of buckets. Each bucket is sorted individually (it is possible to use a different sort algorithm or to continue to sort by using a bucket sort recursively).

Bucket sorting and bucket sorting algorithmsSort buckets
Bucket Sort is a variant of base sorting. Instead of counting arrays, keywords are temporarily stored in different buckets. Read one:
Sorting sequence 123 234 45 111 6 128
The whole process is constantly allocated and collected. In addition, each bucket is a que

This article by @ To stay for the original, reproduced please indicate the source.Summary: This sorting algorithm is not a comparison sort, and on average his time cost is O (n), and it assumes that its input data is evenly distributed across a fixed interval.idea: bucket sequencing Assuming that his input is evenly distributed across a fixed interval, and that it divides the interval into homogeneous sub-intervals, each sub-interval is called a

The following problems are provided in the link:
The king prepared 1000 barrels of wine for his birthday banquet after 10 days. Unfortunately, two of them were poisoned. In order to determine the two barrels of liquor, some people proposed to try the drugs with the death penalty. The incubation period is 10 days.Q: How many prisoners are required to find out the drugs? How is the solution implemented?
This question seems to be a simple extension of the problem where one

Algorithm --- bucket sorting and base sorting, algorithm --- bucket Base
Bucket sorting is no longer a comparison-based sorting method. It is a clever sorting method, but this sorting method requires that the sequence to be sorted meet the following two features:
All values of the columns to be sorted are in an enumerated range;
The enumerated range of the column

In large data high concurrent access, there is often a service or interface in the face of the explosion of the request is not available, or even triggered a chain reaction caused the entire system crashes. At this point you need to use one of the technical means to limit the flow, when the request reached a certain number of concurrent or rate, it is waiting, queuing, demotion, denial of service and so on. In the current limit, the two common algorithms are leaky

Solution One: compare elements are equal
Idea Explanation:
This should be the first solution that ordinary people think of, first get to the array after the small to large sort, and then initialize a min=0 (representing the beginning of the new number), and then iterate over each element of the new array, if two elements are not equal, Count equals i-min, and then I assigned to Min, When I traverse to the last element, count equals the length of the array-min (here's min is the first ele

-Populate the target array: Place each element I in the C (i) of the new array, subtract C (i) minus 1 for each element(3) Code#include Two: Cardinal sort(1) Base orderThe problem above is the sorting of multiple keywords, but the single keyword can still be used this way. Cardinal Order is to sequentially assign each group of keywords in the data that you want to queue. For example, the following sequence: 278, 109, 063, 930, 589, 184, 505, 269,
