If a number with trailing zeros is reversed,are the zeros dropped.ie 700 becomes 007 which becomes 7?

This kata is almost a duplicate of this older one. The difference is essentially there we must return the palindromic number itself (or -1 if not found) and not the number of iterations. I've used the same code with very few cosmetic changes and it passes both.
I don't know if this should be marked as an issue...

• Node 12.x should be used

• The tests should not have global variables

Anyway, the tets are flawed because they use a global variable too, and you can rise it as an issue.

Oh god damnit I feel like such a moron. Thanks hobovsky.

No globals either.

That's a lie, and it's the cause of your problem ;)

yes sir.

Does your solution pass the test case Test.assertEquals( howManyIterationsNeeded(196),null); correctly?

Yep, I've implemented maxIter to terminate. I'm able to pass 44000 tests in ~3 seconds, 0 failed, yet always get Exit Code 137 and browser crash. No globals either.

• do you account for non-terminating inputs (i.e. Lychrel numbers)?
• do you use any global variables?

Is anybody able to do this without getting Exitcode 137? Why are there over 40k tests...my browser keeps shitting the bed and crashing.

Does optional arguments belong in 7 kyu? I wonder.

OK, thanks for the explanation!
