My task is to return the total time taken to remove all the screws, in seconds

EXPLANATION CODE:
1) The function sc calculates the sum based on the screws array. It initializes the sum variable to 1. Then, it iterates through the screws array starting from the second element. For each iteration, it compares the current screw with the previous screw. If they are equal, it adds 2 to the sum; otherwise, it adds 7. Finally, it returns the calculated sum.
