All tests worked until your code timed out, it's not fast enough. Try another way.

Looks like there is an extra space before the E

Most probably it's because of the complexity of the algorithm. Try to find a solution which needs less time to do the calculation! ;)

I have my Tests Passing with

Time: 592ms Passed: 19 Failed: 0
Test Results:
 Basic
 Basic tests (6 of 6 Assertions)
 Test prime (5 of 5 Assertions)
 Test not prime (8 of 8 Assertions)
Completed in 1.84ms
You have passed all of the tests! :)

but I am getting this Error when Running my attempt:

Passed: 0 Failed: 1 Errors: 1 Exit Code: 1
Test Results:
Execution Timed Out
 STDERR
Execution Timed Out (12000 ms)

All tests before it times out isn't the same as all tests. Improve your algorithm.

Print the input.
