Explain Caesar cipher with help of example.

Use Atbash Cipher that is given in code $3$

$N Z G S V N Z G R X H=$_____

A message like $"\mathrm{Good} \mathrm{Morning}"$ written in reverse would instead be $"\mathrm{Doog} \mathrm{Gninrom}".$ In the same way decode the sentence given below:

$"\mathrm{Ot} \mathrm{dnatsrednu} \mathrm{taht} \mathrm{scitamehtam} \mathrm{nac} \mathrm{eb} \mathrm{decneirepxe} \mathrm{erehwreve} \mathrm{ni} \mathrm{erutan} \mathrm{dna} \mathrm{laer} \mathrm{efil}"$

In a certain code, if the word $\text{'}P H O N E\text{'}$ is coded as $\text{'}S K R Q H\text{'}$, how will $\text{'}R A D I O\text{'}$' be coded?
