I need help with this assignment (Java): this is the original assignment https://www.chegg.com/homework-help/questions-and-answers/please-help-program-java-faster-sorting-letters-united-states-postal-service-encourages-co-q10589181
So far I have done zipcode to barcode conversion and it compiles well. But now I need to convert barcode to zipcode. It has to be done in "public String toZipCode (String bc)" method
Here is the code:
