Initialize an empty list device_counts to store the count of security devices for each row that has at least one device.
Iterate through each row in the bank array.
- For each row, count the number of '1's (security devices) and store the count in device_counts if it is greater than zero.
Initialize a variable total_beams to 0, which will store the total number of laser beams.
Iterate through the device_counts list.
- For each pair of adjacent counts, multiply them and add the result to total_beams.
Return total_beams as the final result.
