Bitwise exponentiation
WebJun 8, 2024 · Now assume that x = x 0 + 2 k x 1 , where x 0 is a known part and x 1 is not yet known. Then. g x 0 + 2 k x 1 ≡ y ( mod 2 d). Multiplying both parts with g − x 0 , we get. g 2 k x 1 ≡ ( g − x 0 y) ( mod 2 d). Now, squaring both sides d − k − 1 times we can obtain the next bit of x , eventually recovering all its bits. 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)):
