Modify the "LinkedStackOfStrings.java" program given in blow by adding a method "find()" that takes a string as an argument. It should return true if the string argument is in the linked stack and false otherwise.

The main method should also be modified so that all the strings (other than the search string) inputted by the user are stored on the stack before calling the find() method.

Sample runs would be as follows.

>java LinkedStackOfStrings hello

this

is a

test run

for the

hello program

hello exists in the linked stack

>java LinkedStackOfStrings winter

hello world

is the first program

of any programming

language

winter does not exist in the linked stack
