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)

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. knock off sleep number beds
