Write a C program to do the following:

$($a$)$ Get a string S

$($b$)$Write an user defined function to do the encoding each character in the string $S$ as follows:

$($i$)$Convert the alphabet a to $z,b$ to $y,c$ to xdots.$m$ to n vice versa

$($ii$)$Convert the alphabet A to $Z,B$ to $Y,C$ to xdots.$M$ to N vice versa

$($iii$)$Convert the numeric digit $0$ to $9,1$ to $8,2$ to $7$dots$\mathrm{.}4$ to $5$ vice versa

$($iv$)$ Convert the special character to dot $(.)$

$(5M)$

Example: If the input String is AbC # $123,$ the output should be ZyX $\mathrm{.}876$
