  • Stop Id
  • Route
  • Train number ( 4 character alphanumeric )
  • Time arriving
• Customers can request a schedule from a given time
  • A schedule will be returned if there are two or more coming at that time
  • If there are no more trains coming at the end of the day show the first trains from the next day
  • If there are one or fewer trains arriving no times will be shown

How to run this program

• Build the project and dependencies by running go mod init src/github.com/GoKate206 ( Make sure that there is no leading slash at the end of GoKate206)
• Navigate to src/github.com/GoKate206
  • Run the tests go test *.go -v
  • Run the program go run main.go

Assumptions

• Return value is a slice of struct with schedule details
• There is no given range from requested time ( ex: User wants to see a bus at 3:30 they will not see buses that come at 3:31 )
• Time is in military for comparisons
