: As a learning tool, these drills are highly effective for modularizing code. However, they can be unforgiving; for example, input drills often "break" if a user enters a string like "pizza" instead of a number, highlighting the need for robust error handling. 2. Chemistry & Biochemistry (Peptide Sequencing)

: Usually involves creating a "Drill" class or managing user input in a loop.

: Defining dielectric layers or drill holes in a multilayer Printed Circuit Board (PCB).
