WebMar 11, 2013 · 4 Answers Sorted by: 12 Following what Oli Charlesworth says, you can build DFA for divisibility of base b number by a certain divisor d, where the states in the DFA represent the remainder of the division. For your case (base 2 - binary number, divisor d = 3 10 ): Note that the DFA above accepts empty string as a "number" divisible by 3.

WebJun 15, 2024 · Given a string of binary characters, check if it is multiple of 3 or not. Examples : Input : 1 0 1 0 Output : NO Explanation : (1 0 1 0) is 10 and hence not a multiple of 3 Input : 1 1 0 0 Output : YES Explanation : (1 1 0 0) is 12 and hence a multiple of 3 Recommended: Please try your approach on {IDE} first, before moving on to the solution.
