Exercise $1$: $($Practice with Perl$)$

Suppose you're given the following arrays containing participant information:

@usernames $=("$Sarah$1",$ "Sarah$2",$ "sarah$3",$ "sArah$4")$;

@scores $=(10,7,42,3)$;

Write a program that outputs the participant information, sorted in one of the following ways:

$($a$)$ ASCII$-$betical by participant username

$($b$)$ case$-$insensitive ASCII$-$betical by participant username

$($c$)$ numerical order by participant score $($lowest to highest$)$

$($d$)$ reverse numerical order by participant score $($highest to lowest$)$
