Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
because you're putting spilt, not split?
I am getting the following test cases failing:
Get functions work with no temperatures stored
get_max() doesn't work. Expected but got 110.
get_min() doesn't work. Expected but got 2.
get_mean() doesn't work. Expected but got 31.25.
get_mode() doesn't work. Expected but got 110.
But there is literally no way for it to get those values if there are no temperatures stored.
I've run this locally too, and when there are no temperatures stored, I get nulls. I'm initializing the mean, mode, min and max as nulls and only recalculating them via the insert method. If no values are inserted, then the insert value hasn't been called and there is literally no way for them to return anything but null.
Have I misunderstood something here? Or are the test cases just dodgy?
