In ancient China, farmers always bothered their heads about caculating the amount of their livestock.
Today, we are going to help the farmers to calculate.
In one farm, some of rabbits and chickens live together, and we can get their total number and thier total legs.
Suppose the total number of rabbits and chickens is "a", and the total number of their legs is "b".
Plese help the farmers calculate the exact number of rabbits and chickens by using a and b.
There are 2 inputs.
First is the totoal number of animal, and the second is the totoal number of their legs.
The number will be less than 2*1010 and bigger than or equal to 0.
Print number of the chicken and rabbit respectively.
