Book Filter LLD

LLD in Go = roflmao (Amazon's example was a bookfilter that inherited)

So instead of a bookfilter example we are going to look at enums!

type Season int64

const (
    Summer Season = 0
    Autumn        = 1
    Winter        = 2
    Spring        = 3
)

const (
    Summer int = 0
    Autumn     = 1
    Winter     = 2
    Spring     = 3
)

// string mapping
const (
    Summer string = "summer"
    Autumn        = "autumn"
    Winter        = "winter"
    Spring        = "spring"
)
