Approved

python new test framework is required. updated in this fork

More tests should be added to invalidate such solutions

Yes, but 6 and 7 are incorrect, because the next correct number after 1 is 2, which doesn't appear. Therefore, all that comes after 1 is missplaced and should be included in the returned list. I changed the description to "Incorrect page numbers may appear next to each other".

Solved now.

True Story

no example

I think the description is not clear at all and doesn't allow users to properly handle tested cases. It should be stated clearly that 1 may not be in the list and user is expected to return the whole input array in that case.

According to description: Incorrect page numbers will not appear next to each other

Got this in a random test:

[243,216,187,4,5,6,7,8,9,10,11,12,353,14,15,93,17,18,19,3,21,122]

hi,

the example isn't visible anymore in the description, only it's result (surely related to a markdown update)

Thank you for pointing that out to me.

solution setup is incorrect (lacking the colon)

Thank you for the feedback, I've implemented random testing.

Thank you for the generous feedback, these tests have been implemented.
