以下是必需的程序。
public class Tester { public static void insertionSort(int array[]) { int n = array.length; for (int j = 1; j < n; j++) { int key = array[j]; int i = j-1; while ( (i > -1) && ( array [i] > key ) ){ array [i+1] = array [i]; i--; } array[i+1] = key; } } public static void main(String a[]){ int arr[] = {21,60,32,01,41,34,5}; System.out.println("Before Insertion Sort"); for(int i:arr){ System.out.print(i+" "); } System.out.println(); insertionSort(arr); //sorting array using insertion sort System.out.println("After Insertion Sort"); for(int i:arr){ System.out.print(i+" "); } } }
输出结果
Before Insertion Sort 21 60 32 1 41 34 5 After Insertion Sort 1 5 21 32 34 41 60
