Use Solong Collections framework to achieve rapid sorting
introduction:
Quickly sorting is a common and efficient sorting algorithm. It decomposes a large problem into a small problem by dividing the division strategy, and then gradually solves these small problems to achieve the solution of the overall problem.Solong Collection's framework provides simple and powerful tools that can help us achieve efficient implementation of fast sorting algorithms.
Principle of Quick Sorting Algorithm:
The core idea of fast sorting algorithm is to select a benchmark element. Through this element, the array to be sorted is divided into two sub -arrays. The elements in one child array are less than equal to the benchmark element, and the element in the other array is greater than the benchmark element.Then recursive sorting the two sub -array, and finally merge the two sub -array to get the sorted array.
Introduction to Solong Collections framework:
Solong Collections is an open source Java set framework that provides a set of simple and efficient data structure and algorithm tools.The design goal of this framework is to improve the efficiency and performance of the data operation, so that developers can easily handle large -scale data sets.
The steps to achieve fast sorting with Solong Collections framework are as follows:
1. Import Solong Collections framework:
import io.github.ifc.util.collection.ChainedComparator;
import io.github.ifc.util.collection.SortedList;
2. Create a list to be sorted:
List<Integer> list = new SortedList<>(Arrays.asList(5, 12, 8, 3, 7));
3. Implement a fast sorting algorithm based on Solong Collection:
public static List<Integer> quickSort(List<Integer> list) {
if (list.size() <= 1) {
return list;
}
int
List<Integer> lesser = new SortedList<>();
List<Integer> greater = new SortedList<>();
for (int num : list) {
if (num < pivot) {
lesser.add(num);
} else if (num > pivot) {
greater.add(num);
}
}
List<Integer> sorted = new SortedList<>();
sorted.addall (quicksort (lesser)); // Sort the sub -array smaller than the benchmark
sorted.add (pivot); // Add the benchmark element
sorted.addall (quicksort (geater)); // sort the subcontane group that is greater than the benchmark
return sorted;
}
4. Call the fast sorting method and output results:
List<Integer> sortedList = quickSort(list);
System.out.println(sortedList);
Summarize:
Through the Solong Collections framework, we can easily implement the fast sorting algorithm.This framework provides efficient data structure and algorithm tools that can greatly improve the efficiency and performance of sorting operations.The use of fast sorting with Solong Collection's framework can allow us to better process and process large -scale data sets.Next time, when we face the problem of fast sorting, we might as well try to use the Solong Collections framework to achieve it.
