You must have noticed that some issues share identical identifiers with this particular problem, yes, all of these queries were intended to achieve the same objective.

Input

The input comprises a sequence of integer pairs (a, b), each separated by spaces, with one pair provided per line.

Output

Each pair of input integers $a$ and $b$ should produce their sum, which should be printed on a single line, such that each line of input corresponds to exactly one line of output.
