Both Zero, Negative or Positive

Write a function that returns True if both numbers are:

• Smaller than 0, OR ...
• Greater than 0, OR ...
• Exactly 0

Otherwise, return False.

Examples

both(6, 2) ➞ True

both(0, 0) ➞ True

both(-1, 2) ➞ False

both(0, 2) ➞ False

Notes

Inputs will always be two numbers.
