import java.util.*;
class Lsearch
{
     public static void main(String args[])
     {
          int c, n;
      double array[], search;
      Scanner in = new Scanner(System.in);
      System.out.println("Enter  number  of elements");
      n = in.nextInt();
      array= new double[n];
      System.out.println("Enter those " + n  +" elements");
      for (c = 0; c < n; c++)
         array[c] = in.nextDouble();
   System.out.println("Enter value to find");
   search= in. nextDouble ();
   for (c = 0; c < n; c++)
   {
        if (array[c] = search) /* Searching element is present*/
        {
            System.out.println(search + " is present at
            location" + (c + 1) + ".");
            break;
        }
     }
     if (c = n) /* Element to search isn't present */
     System.out.println(search + " isn't present in array.");
     }
}
