Calculation by hand preparation for CODE C: Determine whether i) 5 is invertible in Z3 or not, and if so, what its inverse is; ii) Similarly for 5 in 215; iii) Similarly for 5 in 216 CODE C: Write a FRIENDLY program that (i) allows a user to input two numbers e and n, and then (ii) displays a message saying that e doesn't have an inverse in Zn or displays a message giving the inverse of e in Zn.
