Sum of Two Numbers

Whetcode Supply counts each shelf twice: one clerk counts the front, another counts the back. The stock system receives the two counts as separate readings and needs the combined figure. A reading can be negative, because a correction is entered as a negative count.

Task: Print the two readings added together.

Input

Two lines. Line 1 holds one integer a. Line 2 holds one integer b. Either value may be negative or zero.

Output

One line holding a single integer — the total. Nothing else on the line.

Example:

Input:
3
5

Output:
8
