Question $1[5$ marks$]$

Implement a generic method, Search, that searches the specified element within an array using linear

search algorithm. Method Search should compare the value with each element in its array parameter until

the value is found or until the end of the array is reached. If the value is found, return its location in the

array; otherwise return $-1.$

Question $2[5$ marks$]$

StringBuilder object. For example, if a StringBuilder object sb$=$This is to test whether the extension

method count can return a right answer or not$,$ the number of words contained in sb is $16.$
