Pascal. Found ambiguous situation when factnums 108385155241100 and E8385155241100 are decoded to same 91160968664 dec. My solution passed to submit from time to time. Please update the description about ambiguous decoding and add this case to Fixed tests.

I passed it using $part2 only :)
Not sure if wrong order is broken, just got pissed from the idea that empty string considered a part of original string "empty" test.

Oh,my bad, thx

I am getting this on Attempt. Year 74 is definetly in the 1st century and I checked it's type - number.
So, my script is working right. Maybe it can be connected to script length check somehow, cause I got this on 75+ chars script.
Putted console.log(typeof n, n) right in the beginning of a function.
Random tests: number 74 - expected '2nd' to equal '1st'

P.S. ws=n=> should probably be wc=n=> because it comes from What Century most likely
