11.17.2.Use the BinarySearch() method to search intArray for the number 4: BinarySearch() returns a negative value

using System;



class MainClass

{



  public static void Main()

  {

    int[] intArray = {5, 2, 3, 1, 6, 9, 7, 14, 25};

    Array.Sort(intArray);

    

    int index = Array.BinarySearch(intArray, 4);

    Console.WriteLine("Array.BinarySearch(intArray, 4) = " + index);

  }



}

Array.BinarySearch(intArray, 4) = -4
