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.

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. WebImplement pow (x, n), which calculates x raised to the power n (i.e., x n ).
