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. WebSo, at 1st iteration a changes to a * a, then a * a changes to (a * a) * (a * a) and so on. And also in each iteration, we multiply current value of a in ans, whenever we encounter a digit of b in binary form, which is equal to 1. Processing: 1.
