C PROGRAM FOR Mth LARGEST AND Mth SMALLEST ELEMENT IN AN ARRAY

  Consider the following I/O samples.

SAMPLE INPUT: 6

                            2 4 5 1 6 3 

                            2

SAMPLE OUTPUT:  5    //2nd largest element

                                 2    //2nd smallest element

The algorithm used here is :

1. Input the number of elements.
2. Input the array elements.
3. Input the Mth value.
4. Sort the array.
5. Print the output for Mth largest and Mth Smallest.

C PROGRAM:  

#include<stdio.h>

int main()

{

int n,a[100],i,j,m,temp;

printf("Enter the number of elements:");

    scanf("%d",&n);

printf("Enter the array elements:");

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

    scanf("%d",&a[i]);

printf("Enter the Mth Value:");

    scanf("%d",&m);

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

{

    for(j=i+1;j<n;j++)

    {

        if(a[i] > a[j])

        {

            temp=a[i];

            a[i]=a[j];

            a[j]=temp;

        }

    }

}

printf("\nMth Largest Element is : %d\n",a[n-m]);

printf("Mth Smallest Element is : %d",a[m-1]);

return 0;

}

OUTPUT:

The given source code in C program "to find the Mth largest and smallest element in an array" is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
