Plus Minus
EasyP3Coding
Return three strings: the fraction of elements that are positive, the fraction that are negative, and the fraction that are zero, in that order. Each fraction is count / n formatted with exactly six digits after the decimal point.
For an empty array return ["0.000000", "0.000000", "0.000000"].

Example 3
- Input
- nums = []
- Output
- ["0.000000","0.000000","0.000000"]
Constraints
- 0 <= nums.length <= 10^5
- -10^9 <= nums[i] <= 10^9
