question in math
Let u, v, w be three binary vectors such that every two of them are at Hamming
distance exactly d from each other.
1. Prove that d is even.
2. Prove that there is exactly one vector at distance d/2 from u, v, w.
the first one i succeeded to solve somehow, but how to solve the second one?
