I LOL'd....but I'm a nerd

Linked Lists aren't stacks. link lists are usually FIFOS not LIFOS. I usually use collections for this stuff which takes care of it all for you and you don't care how it's done under the hood.

doubly linked lists? hash tables?

hey, you guys remember push pops?

I think he was just extending the programming joke, not implying linked lists and stacks are the same thing

better: http://en.wikipedia.org/wiki/Hashtable

List lists are just am implementation that you can use to make a LIFO or a FIFO.

right...I'm just saying...stop being so testical

I vividly remember working 20 hours on a major java hash table implementation in data structures and failing hard because I was distracted by pushing and popping a vagina =[

it's super hard to do hashtables in java.
import java.util.Hashtable

Hashtable ht = new Hashtable();

whoah.

y'all are reminding me why I got out of Comp Sci

that's different. we had to make everything from scratch, re sizable tables and all. could only import Math.random. formulate a key, no collisions, keep complexity at an absolute minimum, huge data set, blah blah... so yeah, it was hard.

with the stuff that I do on a daily basis, that seems super easy.

of course it is, you program every day, i still struggle writing a mathematical proof...i did alright on the GRE but i still wonder how i graduated. oh yeah, my degree isn't worth shit.

I don't write proofs. I do write a lot of algorithms, but it's mostly in my head with set theory scribbles.
