I submitted Clock, the tests run successfully locally (including those marked with `pending`

), but timeout on the server.

```
object Clock:
// https://docs.scala-lang.org/scala3/book/types-opaque-types.html
opaque type Clock = (Int, Int)
// Integer division truncated toward negative infinity
private def floorDiv(x: Int, y: Int) =
val q = x / y
if (q * y == x || math.signum(x) == math.signum(y)) then q
else q - 1
def apply(hour: Int, minutes: Int): Clock =
val hr = Math.floorMod(hour, 24)
val min = Math.floorMod(minutes, 60)
val h = floorDiv(minutes, 60)
val x = Math.floorMod(hr + h, 24)
(x, min)
def apply(minutes: Int): Clock =
apply(0, minutes)
extension (x: Clock)
def + (y: Clock): Clock = Clock(x._1 + y._1, x._2 + y._2)
def - (y: Clock): Clock = Clock(x._1 - y._1, x._2 - y._2)
