### Problem Statement

You are given two integers $a$ and $b$ ($a≤b$). Determine if the product of the integers $a$, $a+1$, $…$, $b$ is positive, negative or zero.

### Constraints

• $a$ and $b$ are integers.
• $-10^9≤a≤b≤10^9$

### Partial Score

• In test cases worth $100$ points, $-10≤a≤b≤10$.

### Input

The input is given from Standard Input in the following format:

$a$ $b$


### Output

If the product is positive, print Positive. If it is negative, print Negative. If it is zero, print Zero.

### Sample Input 1

1 3


### Sample Output 1

Positive


$1×2×3=6$ is positive.

### Sample Input 2

-3 -1


### Sample Output 2

Negative


$(-3)×(-2)×(-1)=-6$ is negative.

### Sample Input 3

-1 1


### Sample Output 3

Zero


$(-1)×0×1=0$.
