Write a program that finds out HCF of two numbers a and b.
What Is HCF?
HCF or Highest Common Factor is the greatest common divisor between two numbers.
For example:
Let there be two arbitrary numbers such as 75 and 90.
75 = 3 * 5 * 5
90 = 2 * 3 * 3 * 5
Common Divisor = 3 * 5 = 15
Here, the HCF of the three given numbers would be 15 since it divides every given number without leaving a fraction behind.
Solution of Reverse digits of a Number :–

import java.lang.*;
import java.io.*;
public class Main
{
public static void main (String[] args) throws java.lang.Exception
{
//your code here
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int k = sc.nextInt();
int arr[]=new int[n];
for(int i=0;i<n;i++)
{
arr[i]=sc.nextInt();
}
Arrays.sort(arr);
System.out.println(arr[0]-arr[n-1]);
}
}
