此代码正确排序。这是插入排序吗?
import java.util.Scanner;
public class InsertionSort {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter the number of elements: ");
int count;
count = sc.nextInt();
int[] a = new int[count];
System.out.println("Enter elements: ");
for(int i = 0 ; i<count;i++){
a[i] = sc.nextInt();
}
int j,temp;
System.out.println("aftr insertion sort :");
for(int i = 1 ; i<count;i++){
j=i;
while(j>0 && a[j-1] > a[j] ){
temp = a[j];
a[j] = a[j-1];
a[j-1] = temp;
j--;
}
}
for(int i = 0 ; i<count;i++){
System.out.print(a[i]+" ");
}
}
}
答案 0 :(得分:2)
我专注于三个for
循环中的第二个循环,即实际排序发生的循环。那个循环对我来说很好。
