Write a recursive function that computes the length of a string.

You cannot use the len function while computing the length of the string. You must rely on the function you are writing.

Put this function into a program that prompts the user to enter a string and then prints the length of that string.

Hint: start by tracing the program in section 3.7.3 to understand how it works.

3.7.3 Reversing a String def revString (s): if s -- "": return"" 4 restrev revString(s[1:1) first = s[0:1] # Now put the pieces togethe result = restrev + first 6 10 return result 12 13 def main(): 14 15 16 if name 17 print (revString ("hello")) main": main ()
