It already does!

"If no temperatures have been inserted yet, the get functions should return null objects."

Thanks! Great idea - I made it really clear that the get functions should take O(1) time.

Great, thanks for the feedback. I made the description more explicit.

Hmm, I can't replicate this. Can you please post your entire solution?

It's not a problem with timing since you're getting that error message.

Hmm, this sounds pretty bad. Good thing you caught this. What language are you using?

Also, can you reply with your get_mode() function? Marked as being a spoiler, or course :)

Awesome, thanks for this feedback @taw and @nedsociety. I'll change the test so it gives a helpful error message instead of relying on the default timeout. I can definitely see how it would be less frustrating.

Do you mean stress testing in general is lame, or that the way I implemented it for this challenge is lame? Do you have a suggestion for how to improve?

Done!

In the description I wrote "If there is more than one mode, return any of the modes." My intention here was that users would always just return a single integer. Do you think there's a better way to handle this?

Awesome, good catch. @wthit56 had the idea to stress test it instead. I'll remove this.

Great, I will:

• Define mode
• Say what to do when no temperatures have been added
• Stress test

Thanks for the feedback!
