Assume that an ArrayList of String objects named arr has been declared and initialized, and the following code is run:

arr. add $("$c$")$;

arr.add $(,0^n)$;

arr.add$(2,L$;

arr.add $(1,0^n)$;

arr.add $(1,""$R$")$;

arr.add $(($:$3,A^{\text{'}\text{'}}\}$;

arr.set $(2,"$D$")$;

arr.set $(2,NO)$;

for$($String str:arr$)($

if $($str$.$compareTo$("$E$")<mtext\; id="EditorElement\_211463"></mtext><mn\; id="EditorElement\_211464">0</mn><mtext\; id="EditorElement\_211465"></mtext><mi\; id="EditorElement\_211466">)</mi>$

system.out.print$($str$+"||")$;

else

System.out.print$("")$;

$\}$

What is the output?

O$||$R$||$L

Al$|$C

A$||$C$|$

O$||$R$||$
