💬 Idea

총 주차 시간을 계산한 뒤 입장료 2 + 첫 주차시간 3 + 이후 주차시간이 있다면 4를 곱하여 반환한다.

💬 풀이

public func solution(_ E : inout String, _ L : inout String) -> Int {
    let e = E.components(separatedBy: ":").map({ Int($0)! })
    let l = L.components(separatedBy: ":").map({ Int($0)! })
    let startHour = e[0]
    let startMinute = e[1]
    let endHour = l[0]
    let endMinute = l[1]
    var time = 0
    
    if startHour < endHour {
        if startMinute > 0 {
            time += 60 - startMinute
        } else {
            time += 60
        }
        
        time += (endHour - startHour - 1) * 60 + endMinute
    } else {
        time += endMinute
    }
    
    if time == 0 {
        return 2
    } else if time <= 60 {
        return 5
    } else {
        return 2 + 3 + ((time - 60) / 60) * 4 + (time % 60 > 0 ? 4 : 0)
    }
}
