Question: Some hash functions do not work as well as theoretically possible. Assume that we use the hash function on integer key i defined by h(i)

Some hash functions do not work as well as theoretically possible. Assume that we use the hash function on integer key i defined by h(i) = i2 mod B

What is wrong with this hash function if B = 10?

How good is this hash function if B = 16 ?

Are there values of B for which this hash function is useful ?
