An automated logistics warehouse generates tracking references for shipping parcels using the following algorithm:
01 destination = input("Enter destination country code")
02 weight = input("Enter parcel weight in kg")
03 prefix = "SHIP-"
04 tracking_ref = prefix + destination + str(weight)
05 while tracking_ref.length < 12
06 tracking_ref = tracking_ref + "0"
07 endwhile
08 print("Tracking Reference: " + tracking_ref)
Define the term casting and state the line number where casting is used in this algorithm.
