WebA simple yet essentially optimal classical algorithm for this general claw-finding problem is the following. Viewing the values of f as a list of N items, we can sort it using N log N + O(N ) comparisons. Once f is sorted, we can for a given y ∈ [N] find an x such that f(x) = g(y) provided such an x exists, using log N comparisons (by ...
