Éowyn has written the function is_odd() to check if a given number is odd or not. Unfortunately, the function does not return the correct result for all the inputs. Help her fix the error.

def is_odd(num)
  num % 1 == 0
end

Examples

is_odd(-5) ➞ true

is_odd(25) ➞ true

is_odd(0) ➞ false

Notes

All the inputs will only be integers.
