Oddness Check
Is it possible to use this code to accurately determine the odd number?
public boolean oddOrNot(int num) { return num % 2 == 1; }
I hope you noticed a trick. If we decide to check a negative odd number in such a way (-5, for example), the remainder of the division will not be equal to one (what does it mean?) Therefore, use a more accurate method:
public boolean oddOrNot(int num) { return (num & 1) != 0; }
It not only solves the problem of negative numbers, but also works more productively than its predecessor. Arithmetic and logical operations are performed much faster than multiplication and division.
