Topic description

Given two integers A and B, their representation is: starting from the one digit, separated by commas "," every three digits.
Now please calculate the result of A+B and output it in normal form.

enter

The input contains multiple sets of data data, each set of data occupies a row, consisting of two integers A and B (-10^9 < A, B < 10^9).

output

Please calculate the result of A+B and output it in normal form, each set of data occupies one line.

sample input

-234,567,890 123,456,789
1,234 2,345,678

Sample output

-111111101
2346912
