Programming Fundamentals/Sorting Arrays

Overview edit

A sorting algorithm is an algorithm that puts elements of a list in a certain order. The most frequently used orders are numerical order and lexicographical order.[1] Most current programming languages include built-in or standard library functions for sorting arrays.

Discussion edit

Sorting is the process through which data are arranged according to their values. The following examples show standard library and/or built-in array sorting methods for different programming languages.

Language Sort Example
C++ #include <algorithm>
sort(array, array + sizeof(array) / sizeof(int));
C# System.Array.Sort(array);
Java import java.util.Arrays;
JavaScript array.sort();
Python array.sort()
Swift array.sort()
Language Reverse Sort Example
C++ #include <algorithm>
sort(array, array + sizeof(array) / sizeof(int), greater <int>());
C# System.Array.Sort(array);
Java import java.util.Arrays;
Arrays.sort(array, Collections.reverseOrder());
JavaScript array.sort;
Python array.sort(reverse=True)
Swift array.sort(>)
