solve in either java or C++

You are expected to implement a project with C++ or Java, which explain below: The Hamming distance dist (u,v) between two binary vectors v=(v1,,Vn) and w=(w1,,wn) is the number of indices k such that vk=wk. A fundamental question in coding theory is to determine the number A(n,d)=max{S{0,1}ndist(u,v)dforalldistinctu,vS}, the maximal number of binary vectors of length n that one can find such that any two distinct vectors have a Hamming distance d. For example, A(5,4)= 2. The Hamming graph H(n,d)=(V,E) is the graph with 2n vertices V given by binary strings of length n. We have (u,v)E if and only if dist (u,v)d. The number A(n,d) coincides with the size of a maximal clique in H(n,d). Find an implement "efficient" algorithms to compute the maximal clique in the Hamming graph (but note that the problem to compute maximal cliques is NPhard). Note that, due to the NP-hard problem, your solution can be exact, approximate, or heuristic
