Hi everyone! Welcome to the Stage 7 of this series of training contests. Cuber QQ is the problem settler of this contest; he has prepared 11 problems for you and wishes you to enjoy it. Good luck!
As the first problem of this contest, Cuber QQ thought that it's reasonable to start with an easy one, so he modified the famous A + B problem by a little bit, so that it's easy enough but not that trivial.
Given $a, b, c$ , find an arbitrary set of $x, y, z$ such that $a\cdot 10^x+b\cdot 10^y=c\cdot 10^z$ and $0 \le x, y, z \le 10^6$.
