- 2Okay, but in actual implementation, doesn't the table.get("Chris") still have to traverse the table to find Chris? How does it know Chris is at a "key" value? When it hashes, what is the actually happening to "Chris"?kylex– kylex2008-11-12 01:41:03 +00:00Commented Nov 12, 2008 at 1:41
- Good question. Will address in a separate answer... If you're impatient, try checking out the Wikipedia article.Daniel Spiewak– Daniel Spiewak2008-11-12 01:43:08 +00:00Commented Nov 12, 2008 at 1:43

- 3NO. A hash table does not ever traverse. It computes a hash of "Chris" and that's the physical slot in the hash table that will have "Chris" as the key. The hash is a computation on the byte values (see MD5 algorithm for details.)S.Lott– S.Lott2008-11-12 10:41:21 +00:00Commented Nov 12, 2008 at 10:41
- thanks for your answer - but how is the hashtable different from say, a dictionary? they both have keys/value pairs. so i'm confused about their difference(s).BenKoshy– BenKoshy2016-02-05 02:55:45 +00:00Commented Feb 5, 2016 at 2:55

How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
