排序一 简单排序

排序中包含两种基本操作：

1 比较两个关键字的大小；

2 将记录从一个位置移动至另一个位置。（或其他类似的操作）

简单排序的时间复杂度为O(n^2)，包括起泡排序，简单选择排序，直接插入排序等，当序列中的记录“基本有序”或n值较小时，简单排序是最佳的排序方法。以java语言描述的代码如下：

package sort;

import java.util.Arrays;
import java.util.Random;

public class SimpleSort {
	public static void main(String[] args) {
		int[] iarr = new int[10];

		Random rand = new Random();
		for (int i = 0; i < iarr.length; i++) {
			iarr[i] = rand.nextInt(1000);
		}
		iarr = new int[] { 9, 8, 7, 6, 5, 4, 3, 2, 1, 0 };
		//iarr = new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
		System.out.println(Arrays.toString(iarr));
		
		// clone方法比Arrays.copyOf方法效率高
		// iarr2 = Arrays.copyOf(iarr, iarr.length);

		int cycletimes;
		int swaptimes;
		// 把较小的数置于数组前端
		System.out.println("simple sort method 1,little first");
		cycletimes = 0;
		swaptimes = 0;
		int[] iarr1 = iarr.clone();
		for (int i = 0; i < iarr1.length; i++) {
			cycletimes++;
			System.out.println("----------------");
			if(i+1<iarr1.length) {
				cycletimes--;
				for (int j = i + 1; j < iarr1.length; j++) {
					cycletimes++;
					if (iarr1[i] > iarr1[j]) {
						int temp = iarr1[i];
						iarr1[i] = iarr1[j];
						swaptimes++;
						System.out.println("inner swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
								+ Arrays.toString(iarr1) + ";temp=" + temp);
						iarr1[j] = temp;
						swaptimes++;
						System.out.println("inner swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
								+ Arrays.toString(iarr1) + ";temp=" + temp);
					}
				}
			}
		}
		System.out.println("method1,cycletimes=" + cycletimes + ",swaptimes="
				+ swaptimes);
		
		// 把较大的数置于数组末端
		System.out.println("simple sort method 2,big first");
		int[] iarr2 = iarr.clone();
		cycletimes = 0;
		swaptimes = 0;
		for (int i = 0, k = iarr2.length; i < k; k--) {
			cycletimes++;
			System.out.println("----------------");
			if(i+1<k) {
				cycletimes--;
				for (int j = i + 1; j < k; j++) {
					cycletimes++;
					if (iarr2[j - 1] > iarr2[j]) {
						int temp = iarr2[j - 1];
						iarr2[j - 1] = iarr2[j];
						swaptimes++;
						System.out.println("inner swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
								+ Arrays.toString(iarr2) + ";temp=" + temp);
						iarr2[j] = temp;
						swaptimes++;
						System.out.println("inner swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
								+ Arrays.toString(iarr2) + ";temp=" + temp);
					}
				}
			}
		}
		System.out.println("method2,cycletimes=" + cycletimes + ",swaptimes="
				+ swaptimes);
		
		// 前端始终保持有序数组，后续元素插入到有序数组中
		System.out.println("simple sort method 3,straight insertion sort");
		int[] iarr3 = iarr.clone();
		cycletimes = 0;
		swaptimes = 0;
		for (int i = 1; i < iarr3.length; i++) {
			cycletimes++;
			System.out.println("----------------");
			if (iarr3[i] < iarr3[i - 1]) {
				int temp = iarr3[i];
				iarr3[i] = iarr3[i - 1];
				swaptimes++;
				System.out.println("outter swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
						+ Arrays.toString(iarr3) + ";temp=" + temp);
				int j = i - 2;
				if(j>=0) {
					cycletimes--;
					for (; j >= 0; j--) {
						cycletimes++;
						if (iarr3[j] > temp) {
							iarr3[j + 1] = iarr3[j];
							swaptimes++;
							System.out.println("inner swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"
									+ Arrays.toString(iarr3) + ";temp=" + temp);
						} else {
							break;
						}
					}
				}
				iarr3[j + 1] = temp;
				swaptimes++;
				System.out.println("outter swap;cycletimes="+cycletimes+";swaptimes=" + swaptimes + ";array:"

			}
		}
		System.out.println("method3,cycletimes=" + cycletimes + ",swaptimes="

	}
}

输出如下：
