POW -_-
also your code for test = 100 gives 192 on my computer whereas I've got WA with your code on this test! (it have outputted 193!)
anyway, casting the function "pow" to "long long int" is not a good choice, instead, you can pre calculate the powers of ten before the main part of your code, here I've changed your code a bit and it've got accepted.
it is because pow function does not work well on it. look at this. : http://ideone.com/ypEdeI I submitted it and it worked
