Would it be different story if the string was HUGE, i mean huge...in the test case? Wouldnt people really need to
write theire own parser in that case? Take down the problem to what it should be, digit by digit, remembering the reminder, take out zeroes at the end, inverting the string, return it. Well, i wrote exaktly that, my own parser, and compared to the work of one row of code and what i had to do, sat whole night and today, trying to figure what is wrong...and louds of code, rows, then 4 kuy is ok. But the easy way in c# to ashieve this, well way to easy if you use the mentioned BigInteger stuff. lol what to say?
Put in a test case with string length of 1000 and se what happens. :)
