Hash Tables

QuestionAnswer
A ___________ is a data structure that stores unordered items by mapping (or hashing) each item to a location in an array (or vector). hash table
In a hash table, an item's ___________ is the value used to map to an index. key
Each hash table array element is called a ___________. bucket
A ___________ computes a bucket index from the item's key. hash function
A common hash function uses the ___________ , which computes the integer remainder when dividing two numbers. modulo operator %
A ___________ occurs when an item being inserted into a hash table maps to the same bucket as an existing item in the hash table. collision
____ handles hash table collisions by using a list for each bucket, where each list may store multiple items that map to the same bucket. Chaining
A hash table with ___________ handles a collision by starting at the key's mapped bucket, and then linearly searches subsequent buckets until an empty bucket is found. linear probing
___________ is a collision resolution technique where collisions are resolved by looking for an empty bucket elsewhere in the table. open addressing
An ___________ bucket has been empty since the hash table was created. empty-since-start
An ___________ bucket had an item removed that caused the bucket to now be empty. empty-after-removal
A hash table with ___________ handles a collision by starting at the key's mapped bucket, and then quadratically searches subsequent buckets until an empty bucket is found. quadratic probing

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
