Write a python program which takes the user input and prints it

backwards with an asterisk between each character. So$,$ if a user inputs

JOHNNY, the program will print $(Y^{**}{N}^{**}{N}^{**}{H}^{**}{O}^{**}{J}^{**}).$ Your program should

use $2$ functions $($main and backwards$).$

Take program $1$ and only print the asterisk for every odd character. For

example, if a user inputs JOHNNY, the program will print $(($:$Y^{**}N{N}^{**}H{O}^{**}(J)$
