Implement a generic method, Search, that searches the specified element within an array using a linear search algorithm. Method Search should compare the search key with each element in its array parameter until the search key is found or until the end of the array is reached. If the search key is found, return its location in the array; otherwise return -1. Write a WinForm app that inputs and searches an int array and a double array. Provide buttons that the user can click to randomly generate integer and double values. Display the generated values so that the user knows what value he/she can search for [Hint: use (IComparable) in the where clause for method Search so that you can use method CompareTo() to compare the search key to the elements in the array]

Question 2[5 marks] Implement an extension method for the class StringBuilder to count the number of words contained in a StringBuilder object.
