Namuk's Chicken Coop

Namuk runs an egg shop and collects eggs from his chicken coop every day. One day he walked in and found that some of the chickens had lost a leg. He wanted to know how many chickens had lost a leg, but there were far too many to count one by one, so he counted every leg in the coop instead.

An intact chicken has two legs, and a chicken that lost a leg has one. Given the total number of legs and the number of chickens, solve Namuk's problem for him.

The first line contains the number of test cases $T$ ($T \le 25$).

Each of the next $T$ lines contains the total number of chicken legs $N$ ($1 \le N \le 300$) and the number of chickens $M$ ($M \le N \le 2M$), separated by a space.

For each test case, print the number of chickens that lost a leg and the number of intact chickens on one line, separated by a space.
