Answer / jyothi
first the given list must be sorted using any of the
sorting tecniques and then taking the kth element in that
resultent array will give the answer
or
another tecnique is using quick sort it will be easier
and time complexity is also very less.sorry i dont have
enough time to write the program here dontmind

Answer / khaja moulali shiak
int kmin(int a[],int n,int k)
{
int i;
int j;
int l;
int u;
int x;
int t;
l=1;
u=n;
while(l<u)
{
i=l;
j=u;
x=a[k];
while((i<=k)&&(j>=k))
{
while(a[i]<x) i++;
while(a[j]>x) j--;
swap(a[i],a[j]);
i++;
j--;
}
if(j<k) l=i;
if(i>k) u=j;
}
return(a[k]);
}

This is a problem of Kth smallest element of QUICK SORT technique

Answer / newclient
sorting is not required in this case.u can still use same
technique(not exactly) as mentioned in Cormen.an algorithm
named "QuickSelect" which has an average complexity of
O(nlong(n)).
Anyways to reduce the number of comparisions one can use
tournament algorithm and for kth element we have to
recursively go through the loosers list.

#include <stdio.h>
#include<conio.h>
main()
{
int a[20], i,n;
printf("ent how many elements u want to enter");
scanf("%d",&n);
printf("enter the elements");
for(i=1;i<=n;i++)
scanf("%d",&a[i]));
s=a[1];
for(i=2;i<=n;i++)
{
if
{
s>a[i]
s=a[i]
}
}
printf("the smallest element is %d",s);
}
hope this correct if it is wrong plz let me know
