Questions & Step-by-Step Solutions
What is a potential drawback of using a hash table?
Steps
Concepts
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 table.
Step 3: Know that to handle collisions, hash tables often need extra space. This can include additional arrays or linked lists.
Step 4: Recognize that this extra space can lead to using more memory than simpler data structures like arrays.
Step 5: Conclude that while hash tables are fast, they can be less memory efficient due to the need for handling collisions.
