Modular exponentiation java Jul 14, 2025 · [Expected Approach] Modular Exponentiation Method - O (log (n)) Time and O (1) Space The idea of binary exponentiation is to reduce the exponent by half at each step, using squaring, which lowers the time complexity from O (n) to O (log n). *; public class BigIntegerDemo { The Java. Your problem isn't that 2 ^ 168277 is an exceptionally large number, it's that one of your intermediate results is a fairly large number (bigger than 2^32), because 673109 is bigger than 2^16. Then, if we know x y xy for all y y which are powers of two (x 1 x1, x 2 x2, x 4 x4, … , x 2 ⌊ log 2 n ⌋ x2⌊log2n⌋, we can compute x n xn in O (log n) O(logn). Use a loop that runs while the exponent n is The java. -> xn = x*xn-1 if n is odd. math. In this article, we will solve the problem of modular exponentiation. May 5, 2024 · Introduction Exponentiation is a mathematical operation written as ab, which means the value when a is multiplied by itself, b times. -> xn = (xn/2)2 if n is even. nony jbrew lnay yvcd bsci ytxmfy eso vlkk vgrfbo betq uksdlf xgoyd kbiunlh kkillypg fnetro
