#include<conio.h>
#define SIZE 5
void main()
{
int a[SIZE],n,i,j,temp;
clrscr();
printf("enter the elements ");
for(i=0;i<SIZE;i++)

for(i=0;i<SIZE;i++)

/*QUICK SORT*/
#include<stdio.h>
#include<conio.h>

int split(int [],int,int);
void quicksort(int [],int,int);

void main()
{
int arr[20],n,i;

printf("\nQUICk SORT\n");
printf("Enter the no.of elements:");
scanf("%d",&n);
printf("Enter the elements:");
for(i=0;i<n;i++)
scanf("%d",&arr[i]);
printf("\nArray before sorting:\n");
for(i=0;i<n;i++)
printf("%d\t",arr[i]);
quicksort(arr,0,n);
printf("\nArray after sorting:\n");
for(i=0;i<n;i++)
printf("%d\t",arr[i]);
getch();
}


void quicksort(int a[],int lower,int upper)
{
int i;
if(upper>lower)
{
i=split(a,lower,upper);
quicksort(a,lower,i-1);
quicksort(a,i+1,upper);
}
}

int split(int a[],int lower,int upper)
{
int i,p,q,t;
p=lower+1;

I am given a sequential algorithm that does a routine search on an unordered list. N = 20. The probability that the value x does NOT appear in the list is exactly 60%, and the probability that x DOES appear is 40%. The 3 questions that I could not get were: A) What is the avg number of element comparisons performed when n = 20 and x does NOT appear in the List. (my answer was 20, is this correct?) B) What is the avg number of element comparisons peformed when n = 20 and x DOES appear in the list? C) What is the avg number of element comparisons performed when n = 20. This should be a single number answer they said.   3
