You can check out my implementation .

As array contains only 1 & 2 we just have to count no of 2's. If it is odd then we can't break the array into two sub arrays and if count is even then (count_of_2)/2 --> (let count of 2 is 6 then 3 in each subarray) if all are 1 then print 1 else print -1.Hope this is helpfull to you.

N.B: This might not be the best solution.

Sorry for my bad english...
