Q$1.$ What is the exact output of the following pleces of code?

int $[]$ array $=\{9,5,8,1,11,3,10\}$;

array$[0]=2$;

array $[1]++$;

array$[2]=$array$[0]+$array$[1]$;

array$[3]=$array$[2-1]$;

array $4=$ array.length;

array$[5]=$array$[6]$;

array $[6]--$;

system.out.println $($array$[$i$])$;

int $[]$ grades $=\{30,90,80,50,70\}$;

for $($int $i=0$;$i$ grades. length; $i+=2)$

system.out.println $($grades $[$i$])$;

int $[]$ grades $=\{30,90,80,50,70\}$;

for $($int $i=$ grades.length$-1$; $i0$;$i--$

System.out.printin $($grades $[$i$])$;

int $y=0$;

int $[][]x=\{\{1,3,5\},\{2,4,6\}\}$;

for $($int $i++j++y+=x[i][j]j=0$;$j.$ length; $j++i=0$;$i.$ length; $i++$
