workshop 8

ada beberapa kumpulan data sebagai berikut :
2 8 3 5 6 4 11 1 9
Urutkan kumpulan data di atas menggunakan quick sort serta gambarkan step by step dari sorting tersebut Source Code:
 # include <iostream>
# include <iomanip>
# include <conio.h>
using namespace std;

void q_sort(int[],int,int);

int main ()
{
 int NumList[9]={2,8,3,5,6,4,11,1,9};

 cout<<" Data Sebelum diurutkan: \n";
 for(int d=0;d<9;d++)
 {
 cout<<setw(3)<<NumList[d];
 }
 cout<<"\n\n";
 q_sort(NumList,0,9);
 cout<<" Data setelah diurutkan: \n";
 for(int iii=0;iii<9;iii++)
 cout<<setw(3)<<NumList[iii]<<endl<<endl;

 getch();
}

void q_sort(int numbers[],int left,int right)
{
 int pivot,l_hold,r_hold;
 l_hold=left;
 r_hold=right;
 pivot=numbers[left];
 while(left<right)
 {
 while((numbers[right]>=pivot)&&(left<right))
 right--;
 if(left!= right)
 {
 numbers[left]=numbers[right];
 left++;
 }
 while((numbers[left]<=pivot)&&(left<right))
 {
 left++;
 }
 if (left!=right)
 {
 numbers[right]=numbers[left];
 right--;
 }
 }
 numbers[left]=pivot;
 pivot=left;
 left=l_hold;
 right=r_hold;
 if(left<pivot)
 q_sort(numbers,left,pivot-1);
 if(right>pivot)
 q_sort(numbers,pivot+1,right);
 }
