WebDec 30, 2024 · We have to check whether its binary representation is divisible by three or not by using Deterministic Finite Automata DFA. So, if the input is like n = [1, 1, 0, 0] (binary of 12), then the output will be True. The approach is simple when a number is divisible by 3 then the remainder will be 0, if not then remainder will be 1 or 2.

WebSep 8, 2016 · Refer to this website: How to Tell if a Binary Number is Divisible by Three Basically count the number of non-zero odd positions bits and non-zero even position bits from the right. If their difference is divisible by 3, then the number is divisible by 3. For … WebSep 19, 2024 · 2. 3 is a prime, so only one number needs to be checked if the previous already was checked and its divisibility by 3 is stored as one bit. There are not that many 3 bit numbers to be recognized. They are 0,3 and 6 in decimal. You must get =1 if your number is one of those. Boolean OR that with the stored divisibility.
WebApr 25, 2024 · I know that for a binary number to be divisible by 3 the sum of 1s in even bits mines the sum of 1s in odd bits must be divisible by 3. After some googling, I found that you can do the dfa of it then convert it to cfg and you can get: \begin{align*} S &\to 0S \mid 1A \mid \epsilon \\ A &\to 0B \mid 1S \\ B &\to 1B \mid 0A \end{align*}
WebSince your input is binary, you can easily work in base b = 2 m. If n = ∑ i = 0 r d i b i, clearly n ≡ ∑ i = 0 r d i ( mod p k), and p k ∣ n iff p k ∑ i = 0 r d i.
