Got it, thanks

In the input string you have "2" and "200" not "2" and "2"

Have question for the last test case:

'1 2 2 4 4 6 6 7 7 18 27 72 81 9 91 425 31064 7920 67407 96488 34608557 71899703'
should equal
'1 2 200 4 4 6 6 7 7 18 27 72 81 9 91 425 31064 7920 67407 96488 34608557 71899703'

Can anyone explain why the second 2 should be 200? Thanks
