Corporation

The global business community is buzzing with the latest news! It has just been announced that two leading corporations in Mendeleyevo, "Rosselbank" and "General Store", have decided to merge. The only task left is to calculate their combined capital. This is not straightforward, as the capital of such large corporations can be quite significant, and it can even be negative due to economic crises.

Input
