Use Java! :D


so... I am used to code in C++, and I'd never solved a problem in Java before. I spent like an hour learning the basics, changed all the variables in my K-based Numbers. Version 1 solution to BigInteger in Java and got AC!

question does unfairly favors languages w/ big integer library

if cannot link in library for c++ then can implement by hand [for this question, only 4 ops required: =, +=, *=, output], but consumes time to debug
