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)): WebBinary Exponentiation As the name suggests, it is the computation of a numerical or a binary component whose result can be as little as zero or as complex as ten raised …
