WebOct 19, 2024 · Representing Sets. Bits representation of an integer are 0-indexed and the index starts from right side i.e. least significant bit. So we can represent every subset of the set {0, 1, 2, ..., n-1} as an n bit integer and whose bits indicate which element belongs to the subset. If bit at index 3 is 1 and at index 4 is 0 in binary representation of a number, then … WebIn general, multiplying k times by M gives us F k, F k + 1: Here matrix exponentiation comes into play: multiplying k times by M is equal to multiplying by Mk: Computing M k takes O ( (size of M) 3 * log (k)) time. In our problem, size of M is 2, so we can find N’th Fibonacci number in O (2 3 * log (N)) = O (log (N)):
