Why hash function H (k) = k% m medium m try not to be a power of 2The screenshot below is from Chapter 11 of the clrs discussion on the hash functionI've been confused before, whyWhen using the division method, we usually avoid certain values of M. For example, M should not being a power of 2, since ifm = 2^p, then H (k) is just the p lowest-order bits of K.unless we know, all low-order p-bit patterns is eq
