WebSep 9, 2014 · Start with exponentiation by squaring, as you have. Perform the actual squaring in a 64-bit unsigned integer. Reduce modulo 673109 at each step to get back within the 32-bit range, as you do. Obviously that's a bit awkward if your C++ implementation doesn't have a 64 bit integer, although you can always fake one.

Intuition: While calculating (n^k), binary exponentiation relies on whether n is even or odd. If k is even (n k) can be written as (n 2) k/2. As we can see that computation steps were reduced from k to k/2 in just one step. If k is odd (n k) can be written as n. chula vista tire shop

WebJun 6, 2024 · We can calculate f 1 ( p) in O ( log m) using the binary exponentation algorithm. Similarly for f 2 ( q) . In the first step of the algorithm, we need to calculate f 1 for every possible argument p and then sort the values. Thus, this step has complexity: O ( ⌈ m n ⌉ ( log m + log ⌈ m n ⌉)) = O ( ⌈ m n ⌉ log m) WebExponentiation is frequently used in public key cryptography, and the binary exponentiation method provides a particularly simple implementation.
