Integer Sign Determination
Identify whether a given integer is positive, negative, or zero and return a respective string: "positive", "negative" or "zero".
Input: Integer (int).
Output: String (str).
Examples:
assert determine_sign(5) == "positive" assert determine_sign(0) == "zero" assert determine_sign(-10) == "negative" assert determine_sign(1) == "positive"
How it’s used: understanding the sign of a number can be useful in financial software, scientific simulations, and many algorithms to determine subsequent logic.
Precondition:
- num ∈ Z.
