One day, two mathematicians were walking in the forest and picking
berries. They’d been walking for two hours, and then they stopped and
decided to see who’s got more berries. They took out the scales (can you
imagine a mathematician going to the forest without any scales?) and they
weighed their baskets with berries. They wrote the resulting numbers a_{1} and
b_{1} down on a piece of paper. Then the second mathematician put all his
berries to the first one’s basket (so that his basket became completely
empty) and they weighed their baskets again and they received numbers
a_{2} and b_{2}, correspondingly. At last, the first mathematician put all
the berries to the second one’s basket (so that his basket became completely
empty); they weighed the baskets and got numbers a_{3} and b_{3},
correspondingly. This data was enough to find the winner and the happy
mathematicians moved on. Your task is to calculate the mass of the berries
in each mathematician’s basket by the start of the competition.
Input
The input data consists of three lines. The i’th line (1 ≤ i ≤ 3) contains
integers a_{i} and b_{i} (0 ≤ a_{i}, b_{i} ≤ 10 000).
Output
Output the weight of berries in the basket of the first and the second mathematician correspondingly.
