Problem:
   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 .
