$$ Implement a recursive reverseString in C$++$ function like the one in the pdf$\text{'}$s videos, but with a twist. You are no longer allowed to print out the last character in s$.$ You are, however, allowed to print out the first character in s$,$ i$.$e$.$ s$[0].$

$$ First, make one change to the function so that it prints out the first character in s$,$ s$[0]$ and then calls ReverseString on s minus the last character. Notice that it doesn't work anymore! It no longer reverses the string. Look at what it does and think about why.

$$ What further changes can you make to the function to fix it$?$ In other words, write a recursive function that reverses the string, but you aren't allowed to print out the last character in s$.$ You are allowed print out the first character in s$.$ Useful string functions:

o s$.$size$()-$ returns length of string s

o s$.$substr$($pos$,$len$)-$ returns the substring of s of length len starting at postion pos $($zero is first position$)$
