Write a Java program that implements the $2$D array from Exercise $5.$ Use the logic in your flowchart, or pseudocode, as a guide the input file should be called input.in$.$

Here is an example for a $4*8$ grid and the input string.

And the rest is rust and stardust

$01234567$

$0$ A n d t h e

$1$ s i t s e r

$2$ r u s t a n d

$3$ s u d r a t s

Output string:

A rsnsuudisd trtt ahsateens rd

Your program should work for any input file and any size grid.

Make sure your program only outputs the encrypted string.
