In Interviews If interviewers ask us to implement linkedlist problems we have to write our own linked lists or we can just use predefined classed in java/c# ?

Odds are, he/she wants to know that you are skilled enough to be able to write your own.
And you should be able to answer this easily. Study up.

In my book it is says that "there are non-decidable languages" And the proof is:
Every algorithm is a word. Then there are only countable algorithms.
But there are uncountable languages and therefore more than algorithms.
Why is it said that every algorithm is a word? A word is a concatenation of symbols, elements of an alphabet, then what's the relation between a word and an algorithm? Can anyone explain me that?

The following link mentions some types of dynamic programming:
http://www.mii.lt/olympiads_in_informatics/pdf/INFOL056.pdf
one of which is "broken profile".
I am pretty sure it is a valid term since I have seen references to it in other programming competition sites like TopCoder and CodeForces.
But I can't seem to find anything on this topic. This term has been used mostly by Russian sources.
Does anyone what if means, or what kind of problems within dynamic programming it solves? Or even better a tutorial?

I have no idea, I Googled, no dice.
In context: "Do we have an LOE on this? They keep asking me haha. :)"
I have googled and googled and googled and can't put my hands around it. Could someone explain it to me like I'm five?
Level Of Effort is the most likely one. There are a bunch listed here as well: http://www.acronymfinder.com/Business/LOE.html
I guessed this one because it was in the context of project management, and that's the type of thing a PM needs to know.
And it specifically shows up here: http://www.all-acronyms.com/LOE/tag/project_management as the first Google result of a search for "LOE project management acronym"

The book is full of interesting questions, but since I am learning it myself, it would be a great help if I can find solutions to at least some of the questions.
Anyone knows anything about this?
The book's website, algorist.com has a wiki with solutions.

What does the term "Coding in Vacuum" mean? I have heard the term before but I am unable to find anything on Google that is relevant.
I interpret this as a derogatory comment about someone writing software while not considering the greater context of the project. For example:
"Didn't Bob know that this email client was supposed to handle emails
with images?"
"I guess not, I think he was just coding in a vacuum."
