Positive or Negative number
Detailed guide and Python implementation for the 'Positive or Negative number' problem.
Problem Statement
Write a function check_sign(n) that takes an integer n and returns the string "Positive" if n is greater than zero, "Negative" if n is less than zero, or "Zero" if n is exactly zero.
- •-10^9 <= n <= 10^9
Examples
n = 5
"Positive"
5 is greater than 0, so we return "Positive".
n = -3
"Negative"
-3 is less than 0, so we return "Negative".
n = 0
"Zero"
0 is neither positive nor negative, so we return "Zero".
