Consider the following two programs:

A$.$

public class Test $\{$

public static void main$($String$[]$ args$)\{$

xMethod$(5)$;

$\}$

public static void xMethod$($int length$)\{$

if $($length $>1)\{$

System.out.print$(($length $-1)+"")$;

xMethod$($length $-1)$;

$\}$

$\}$

$\}$

B$.$

public class Test $\{$

public static void main$($String$[]$ args$)\{$

xMethod$(5)$;

$\}$

public static void xMethod$($int length$)\{$

while $($length $>1)\{$

System.out.print$(($length $-1)+"")$;

xMethod$($length $-1)$;

$\}$

$\}$
