1037: 希尔排序
Description
已知希尔排序的部分代码如下,勿改动,请补充实现希尔排序函数,要求输出每趟排序结果,增量序列取值依次为5,3,1。
#include<iostream>
using namespace std;
const int MaxSize=100;
class List
{
private:
int r[MaxSize+1];
int n;
public:
List(){n=0;} //empty list
void InsertR(int k) //表尾插入
{ r[++n]=k;}
void Display(); //display
void ShellSort(); //ShellSort
};
void List::Display()
{
for(int i=1;i<=n;i++)
cout<<r[i]<<" ";
cout<<"\n";
}
int main()
{
List L;
while(1)
{
int k;
cin>>k;
if(!k) break;
L.InsertR(k);
}
//L.Display();
L.ShellSort();
// L.Display();
return 0;
}
