11 is the output of the arr[2][1].
let it understand in a very simple manner.
if we analyze the arr[3][2][2] in a 3d style ,it would be
easy to capture the answer.
1 2
3 4

5 6
7 8

9 10
11 12
here you can see in arr[3][2][2]. there are 3 rows,of 2x2
matrix each.
now coming to the real problem we have to find arr[2][1].
since the last bracket is absent in the arr[2][1].thus we
will implement this by our self.now we may read it as
arr[2][1][0],suppose the last bracket contain 0 in it.

finallly we are ready for finding the value ,
arr[2][1][0].
here [2] = last column of the matrix,since the array is
readed as o ,1,2.
[1][0]= in the third row ,[1][0] represents the value 11.
therefore 11 is output of the arr[2][1][0].
