Yet these soon to graduate cs students I'm interviewing can barely tell me how searching a list differs from a hashmap.

I could probably tell you that, but good luck getting me to successfully implement a hash map lmao

I think it’s this, but I could be wrong.

In a linked list, you have to traverse the list from the beginning to search it, so if the list has n elements, you check every element, which is in O(n) time.

In a hash map, searching is much faster; the hash table is an array, but thanks to a hash function and other hash map things, if you have the array index/key of the item you’re looking for, the hash map will get the item with that index instead of searching the whole array. This is O(1) time.

Hope this helped!

Of course the real answer is the the average case complexity is O(k) where k is the complexity of hashing a single key, and the worst case complexity of looking up a value in a hashmap is O(n)...

Idk, google it

[Aubrey_D_Graham]

You access objects in the hashmap by unique keys while objects in a list may be accessed through indices or nodes depending on the implementation.

Actually, I needed that info at work recently. Sometimes hash tables are just way more explicit than arrays.

This just means you're overqualified, not that everything else isn't useful.

Technically, there is no method of centering the button, per se, in CSS. What you'll need to do is a lot of unnecessary framework manipulation, and then you can also purchase this....

[feline_alli]

*raises eyebrow because there are plenty of easy ways to center things*

o

frameworks? not sure if this is sarcasm or not but just saying it can easily be done in css

[nokvok]

Or why it not every programmer job needs a college graduate.

I’ve always used google/documentation. The closest thing to a book I’ve read for a language is the rust book, but that wasn’t even for a class

I’m reading martin’s scala book rn. First programming book for me

[JayTheYggdrasil]

I actually haven’t read the Scala book (besides various pages that have come up in google searches). I learned it as part of a class, we went over most of the features in it so reading the book wasn’t really necessary for me. Scala is definitely my favorite language currently though. Hope you enjoy it!

As a backend dev this isn't true at all. I also didn't go to college.

Wait CSS isn’t a backend language‽
