Simply find the product of the array. NOTE: Use long long int for all calculations. Integer variables are 32 bit, and can only calculate values precisely upto 10^9. Post that, long long int needs to be used(64 bit) for all calculations.
The constraints were N<=10 and A*<=15, resulting in a maximum possible product of 15^10, which is greater than 10^12.
