This problem is partial judge.
You need to deal with something "big enough".
Each input will contain two big integer a, b which are up to 5000 digits.
You need to calculate a+b and a-b.
The input will end by EOF.
a and b is both up to 5000 digits and separated by a blank
The input will end by EOF
For each input print the result of a+b and a-b.
Each result is end by a \n
