Questions & Step-by-Step Solutions
Which of the following hashing techniques can help reduce collisions?
Step 1: Understand what a hash table is. A hash table is a data structure that stores data in a way that allows for fast access using a key.
Step 2: Learn about collisions. A collision happens when two different keys hash to the same index in the hash table.
Step 3: Know that there are techniques to handle collisions. These techniques help to manage what happens when a collision occurs.
Step 4: Identify the techniques mentioned: chaining, linear probing, and quadratic probing.
Step 5: Understand chaining. In chaining, each index in the hash table points to a list of entries that hash to the same index.
Step 6: Understand linear probing. In linear probing, if a collision occurs, the algorithm checks the next index in the table until it finds an empty spot.
Step 7: Understand quadratic probing. In quadratic probing, if a collision occurs, the algorithm checks the next index based on a quadratic function until it finds an empty spot.
Step 8: Conclude that all these techniques (chaining, linear probing, and quadratic probing) are used to reduce collisions in hash tables.
