PROGRAMMING:Expression evaluation
Xiaoming's cousin is doing his homework. He has been troubled by a problem for a long time. He needs you to use the program to help solve it.
The title is as follows: find the value of Z according to the value of X, y. If x ≥ 0 and Y ≥ 5, it is calculated according to the formula z = 3 * x + 2 * y; If x ≥ 0 and Y < 5, it is calculated according to the formula z = 5 * X-Y; If x < 0 and Y ≥ 0, it is calculated according to the formula z = x + 4 * y; If x < 0 and Y < 0, it is calculated according to the formula z = 3 * X-Y.
###Input format:
Give two integers x, y in one line. The middle is separated by a space. The absolute values of X and y do not exceed 10000.
###Output format:
Output the value of Z on one line.
###Input example:
```in
7 8
```
###Output example:
```out
thirty-seven
```
