Consider the following code segment.

String$[][]$ letters $=\{\{"$A$","$B$","$C$","$D$"\},$

$\{"$E$","$F$","$G$","$H$"\},$

$\{"$I$","$J$","$K$","$L$"\}\}$;

for $($int col $=1$; col $<$ letters$[0].$length; col$++)$

$\{$

for $($int row $=1$; row $<$ letters.length; row$++)$

$\{$

System.out.print$($letters$[$row$][$col$]+"")$;

$\}$

System.out.println$()$;

$\}$

What is printed as a result of executing this code segment?
