        /* Q1

​

Read two strings from the user and compare them. 

            The comparison should ignore a) leading spaces, b) case, and c) trailing spaces. 

Thus, “ hello World” is equal to “hello wORLD          ”.

Show “Equal” if the two strings are equal; “Not Equal” otherwise.

Number of spaces between words matter.

            Q2

​

Create a string “Celebrating 200 year of Indiana University”

Insert “s” after “year”.

You must use Insert and IndexOf to complete this question.

Print out the updated string.
