The following code uses a few standard array operations:

public static void takesAnArray$($int$[]$ arr$)\{$

arr$[0]=0$;

$\}$

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

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}[]a=\{1,1,1,1\}$

takesAnArray$(a)$;

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}[]b=a.$clone$()$;

$b[1]=0$

${\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}[]c=a$

$c[2]=0$

$//$Point $1$

$\}$

What is the value of the array a at Point $1?$
