Questions & Step-by-Step Solutions

Which of the following is a disadvantage of using hash tables?
  • 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: Recognize that handling collisions can be complicated. There are different methods to resolve collisions, such as chaining or open addressing.
  • Step 4: Realize that managing these collisions can slow down the performance of the hash table, especially if there are many collisions.
  • Step 5: Conclude that the complexity of handling collisions is a disadvantage of using hash tables.
