I'll make this as short and to the point as possible, but it's kind of a complex issue. I'm writing in Java on a Linux platform, for whatever that's worth. Short version of the goal: I want to have an abstract class called Client that acts as a generic container for client connections. Client should thread each of its connections. I ...

I've seen various answers to the ball collision detection question explaining why sqrt operations are slow, why absolute value operations are fast on floating ponts etc. How can I find out which operations are expensive and which are not? Basically, I'm looking for a resource where I can learn about the implementation of all the python ...
Is my professor asking me to draw the stack? Does he want me to draw it in action? I feel stupid but it's not like anyone ever told me! Thank you for your help. Wow you guys are quick. Thank you already. The complete question is: Consider two stacks, each of size n (i.e., each one can hold a maximum of n elements). If the sum of the num...
The problem I am trying to solve has a list of intervals on the number line, each with a pre-defined score. I need to return the maximum possible total score. The catch is that the intervals overlap, and of the overlapping intervals I can use only one. Here is an example. Intervals - Score 0- 5 - 15 4- 9 - 18 ...

As I know they're creating iframe then do some black magic there and everything works. The question is: what do those editors do with iframe so it becomes editab...
Is a standard-conforming C++ implementation allowed to implement some behavior that is said to be implementation-defined in the standard in such way that it is different between different runs of the same compiled once program with the same input data? For example, is an implementation allowed to say "the behavior is this on weekends an...

HashMap contains a hash-table which is an array that hold the values as I understood the hash-table has an initial size, yet it can get increased after many invocation of put() (depends on the load-factor) anyhow I wonder how can you find a value after you change the size of the hash-table because I know that in order to calculate the ...

I have a number of data classes, which share an abstract base class so i can work with them generically (sort of). They each have a static method called Lerp, which i use frequently along with a couple of other lines. I wanted to refactor this out into a method because of DRY,but it seems there's no way to do so. How do i get around this...
