The global business community is abuzz 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 determine their total capital. This is not so simple, since the amount of money in the assets of such powerful corporations can be quite large, and moreover, it may even be negative (an economic crisis, nothing can be done).
The input consists of two integers, and , each on a separate line — the capitals of Rosselbank and General Store, respectively, -10^{100} \leq a, b \leq 10^{100}.
Output a single integer equal to the capital of the merged enterprise.
