Dear students,

Using arrays, please write a Java program that simulates assigning seats in a train based on the following seating pattern:

$1$ A B C D

$2$ A B C D

$3$ A B C D

$4$ A B C D

$5$ A B C D

The program should display the initial seat pattern, with an $\text{'}$X$\text{'}$ marking the seats already assigned. For example, after seats $1$A$,2$B$,$ and $4$C are taken, the display should look like this:
