Which of the following hash functions is considered good for a hash table?

Step 1: Understand what a hash function is. A hash function takes an input (or 'key') and produces a fixed-size string of bytes, usually a number.
Step 2: Know the purpose of a hash function in a hash table. It helps to quickly locate a data record given its search key.
Step 3: Learn about collisions. A collision happens when two different keys produce the same hash value.
Step 4: A good hash function should distribute keys evenly across the hash table. This means that each slot in the table should have about the same number of keys.
Step 5: The more evenly distributed the keys are, the fewer collisions will occur, leading to faster access times.
Step 6: Look for hash functions that are simple, fast, and produce a wide range of outputs to ensure good distribution.
