So far in this course, you’ve been working with loops that operate over full ranges; in other words, your loop always goes from start to finish with no interruption.

for i in 0..<daysOfTheWeek.count {
    print("\(daysOfTheWeek[i]): \(poolTemperature[i])")
}

    if daysOfTheWeek[i] == "Thursday" {

    }

    if daysOfTheWeek[i] == "Thursday" {
        break
    }

for i in 0..<daysOfTheWeek.count {
    if daysOfTheWeek[i] == "Thursday" {
        break
    }
    print("\(daysOfTheWeek[i]): \(poolTemperature[i])")
}

    if daysOfTheWeek[i] == "Friday" {

        print("I'm in love")

        continue

print("---")

for floor in 11...15 {
    print(floor)
}

for floor in 11...15 {
    for room in 1...4 {

    }
}

        print("\(floor)-\(room)")

        if room == 1 {
            continue
        }

    if floor == 13 {

    }

    if floor == 13 {
        continue
    }

        if floor == 12 && room == 3 {
            continue
        }

floor_loop: for floor in 11...15 {
    if floor == 13 {
        continue
    }
    room_loop: for room in 1...4 {

        if floor == 12 && room == 3 {
            continue floor_loop
        }
