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

"y=x^2 vs y=x^"Y=x^2, basic functions, nonsense not much to say. y=x^ (1/2), the exponent becomes the reciprocal of the upper form. x^ (1/2) that is, √x. But what does a function image look like? The y=x^ (
In Java, the minimum and maximum values for an Integer are defined as follows:
/**
* A constant holding the minimum value an {@code int} can
* have, -2
The minimum value is -2^31, the maximum value is 2^31-1, why? The derivation process is as follows: the number of digits in the binary code that the Integer actually
