Hi.↵
↵
I'm very interested in binary representation of numbers.I see some attractive formula and methods such as :↵
↵
- (x)&(-x) return smallest significant of x that is 1 !↵
↵
- use binary for create all subsets of a small set :)↵
↵
- ...↵
↵
I want to learn more, so create this blog for sharing interest knowledges and making it worth post for competitive programmers.↵
also I want to know is there a relation about remainder of numbers or divisibility of them in binary ? ( for example in decimal we know a number is divisible by 5 when it's last digit is 0 or 5 )
