算法导论之插入算法JAVA实现

算法导论插入算法源伪代码如下

JAVA实现代码如下

package com.bird.math;

/**
 * @deprecated 算法导论中的插入算法实现
 * @author bird

 */
public class Insert_sort {
	public int[] Insertsort(int[] A){//插入排序算法
		for(int j = 1; j < A.length; j++){
			int key = A[j];
			int i = j-1;
			while(i>=0 && A[i]>key){
				A[i+1] = A[i];
				i = i-1;
			}
			A[i+1] = key;
		}
		return A;
	}
	
	public static void main(String [] args){
		Insert_sort sort = new Insert_sort();
		int [] a = {7,4,9,13,5,1,34,24,235,29};
		a = sort.Insertsort(a);
		for(int i = 0; i < a.length; i++){
			System.out.print(a[i]+" ");
		}
	}
}

运行结果如下

1 4 5 7 9 13 24 29 34 235
