Consider the following code:

#include

#include

int main$()\{$

MysterySequence $*$seq $=$ createMysterySequence$()$;

addSomething$($seq$,"$A$")$;

addSomething$($seq$,"$B$")$;

printf$("\%$s

$",$ removeSomething$($seq$))$;

addSomething$($seq$,"$C$")$;

addSomething$($seq$,"$D$")$;

printf$("\%$s

$",$ removeSomething$($seq$))$;

printf$("\%$s

$",$ removeSomething$($seq$))$;

addSomething$($seq$,"$E$")$;

addSomething$($seq$,"$F$")$;

printf$("\%$s

$",$ removeSomething$($seq$))$;

return $0$;

$\}$

What will be printed if MysterySequence is implemented as a queue, and addSomething and removeSomething are enqueue and dequeue operations, respectively?
