Why Num&sizeMinusOne faster than num&(size-1)
I’ve been told that when I have a hash table of size m and m=2^k, I can use the & operator as num & (size-1) instead of num % size, to fit the hashCode to my table size.

Design Hash table with simple hash function
I want to learn to Design Hash table with simple hash function for better understanding. I understand that the hash table will work as long as the hash function maps each key to a non-negative integer less than the size of the hash table, but it will only perform well if it distributes different keys across different buckets.
