1 is not a prime number

fixed

The biggest problem I encountered in this kata is import

I need some time to think about this problem

Acutally, I haven't any good idea to solve this problem. The only solution I can think of is to remove the restriction

I disabled all __...__
at least I think its useless in this kata

Banned datetime

tbh, this solution beyond my expectation

All right, I misunderstood of 10 - 100000. Maybe I dont understand how the tree generator works

but this sentence is true For a inefficiencies solution, this constitutes a 'lucky test' because I saw that the number of nodes can be extremely large or extremely small. It shouldnt happen (At least

Anyway, good kata. Looking forward to your next kata

Testing tree of 2233 nodes.
Testing tree of 8786 nodes.
Testing tree of 2668 nodes.
Testing tree of 2233 nodes.
Testing tree of 1061 nodes.

Its the result in the large random tests

In the test case, large random test can spawn 10 - 100000 nodes

As you said For this kata a straightforward approach that computes the maxima and minima is sufficient

For a sufficiently efficient solution, thats no impact

For a inefficiencies solution, this constitutes a 'lucky test'

then, whats the point of large random test(for more submission?

Edit: change the range to 10000 - 100000 can constitute efficiency test, but according to your idea its not required

In big random test, the range of n is 0 - 1e5. This can be changed to 1e4 - 1e5 to ensure that all generated numbers are large integer.

Tysm for helping, you are nice

check in test case

Got timed out in the O(log(n)^3)(python) method

I forgot to replace BigInteger method ;/

= given -ne input

Fixed. Can you check the test case in python, maybe its wrong. randint(256, 512) Thats why I use Next(256, 513)
