Simple exercise to play around with the time standard library

14_days.go

package main

// Hello again. This time, we will be exploring the
// time standard library.
//
// The function that we'll make is pretty simple,
// we are going to have a date input, in the form (or type)
// of time.Time, then we'll add 14 days to it.
//
// But here's the tricky part:
// We'll skip satuday and sundays, so the entire 14 days
// should be on weekdays only, not on weekends.
//
// This is the pseudocode:
//
//      var date = given date
//      var days = 0
//      var output = date
//
//      while (days < 14)
//        var dateInDay = convertToDay(output)
//        switch dateInDay
//          case "saturday"
//            output = output + 1 day
//            continue
//          case "sunday"
//            output = output + 1 day
//            continue
//          default
//            output = output + 1 day
//            days += 1
//        end
//      end
//
//      return output
//
// But this pseudocode has a problem:
// What if the date stops at weekends?
// There's your challenge!
// 
// Good luck!
func Add14Days(date time.Time) time.Time {
	var output = date
	// To convert a date to a weekday,
	// use (time.Time).Weekday()
	// https://pkg.go.dev/time#Time.Weekday
	// It will return an enum of Weekday, use that
	// as your advantage!

	// To add a date, use (time.Time).Add()
	// https://pkg.go.dev/time#Time.Add
	// for example:
	// time.Add(time.Hour * 6)
	// this will increment the time into 6 hours
	return output
}
