Input two integers to represent the total number of chickens and rabbits and the total number of feet, write a program to output the number of chickens and rabbits (input and output, according to the order of chicken first and then free, separated by spaces in the middle).
###Input format:
Two non negative integers up to 100000 separated by spaces.
###Output format:
Two integers, separated by spaces, if the input data has no solution, the output: - 1 - 1 (indicating impossible).
###Input sample 1:
```in
10 28
```
###Output sample 1:
```out
6 4
```
###Input sample 2:
```in
18 35
```
###Output sample 2:
```out
