Implementing ConcurrentHashMap in Java
Recently, An interviewer asked me to implement ConcurrentHashMap using basic Data Structures in Java.
The default implementation of ConcurrentHashMap in java is quite complex one.
Would you agree that it's unfair to ask such complex and lengthy question in an interview or Am I missing something ? Is there a simple way to implement ConcurrentHashMap in java using basic DS that can be written in 20 mins ?

Amazon or Startup
I've been working for a startup for about 2 years (joined since the company started) and become senior software engineer in the company, which will get involved with some management stuff.
Now I have a Amazon SDE offer on my plate (Level 1). Should I quit my current job and accept Amazon's offer?
From salary stand point there is no comparison, my current salary just a half of Amazon's base salary.
If I'm going to start a startup after 1 or 2 years, which will help me more. (e.g. experience).

Should I prepare more on dynamic programming problems or focus on other area of algorithms? 
Is my approach correct?
Problem : There is a hill and few taps are present, all connected to other taps above/below, find which tap will be the last one to get water from a spring on the top of the mountain.
My Approach : Now I understand this is a connected graph problem. And by doing Breadth First Traversal we can get the last tap which will get the water.
Doubt : 1. Is my solution correct? If yes, then does BFT always gives the right answer? 2. Is there any other approach I'm not seeing?

I am trying to solve the problem:
http://www.careercup.com/question?id=5186563703046144
I think my logic is right.Correct me if I'm wrong.
My logic is exhaustively traversing the tree in all possible Kstep ways from the root, then selecting the greatest value.
I am having Segmentation Fault.I cant seem to find why.
Thank You for your time.
Code:#include "iostream" //global variables struct tree{ int value =0; struct tree *left=NULL,*right=NULL,*parent=NULL; } *node; //forward declaration inline void initnode(); void evaluate(struct tree*,int,int); //program int main(int argc, char const *argv[]){ //checked OK int k; std::cin >> k; initnode(); evaluate(node,0,k); return 0; } inline void initnode(){ //checked OK node = new struct tree; node>value = 0; node>left = new struct tree; node>left>value = 5; node>left>parent = node; node>left>left = new struct tree; node>left>left>value = 24; node>left>left>parent = node>left; node>left>right = new struct tree; node>left>right>value = 1; node>left>right>parent = node>left; node>right = new struct tree; node>right>value = 6; node>right>parent = node; node>right>right = new struct tree; node>right>right>value = 11; node>right>right>parent = node>right; } void evaluate(struct tree *node,int total,int count){// gdb shows segmenation fault if(node !=NULL){ if(count){ evaluate(node>left,total + node>value + node>left>value, count 1);/ evaluate(node>right,total + node>value + node>right>value, count 1); evaluate(node>parent,total + node>value + node>parent>value, count 1); } else std::cout<< total; // right now I'm displaying all possible 'total' no selection to test the code } }
