<style type="text/css">
/* default styles here for older browsers.

Coding Practices which enable the compiler/optimizer to make a faster program
... foo1, const Foo* foo2, int numFoo, Foo& barOut)
{
for (int i=0; i<numFoo, i++)
{
barOut.munge(foo1, foo2[i]);
}
}
the compiler doesn't know that foo1 != barOut, and thus has to reload foo1 each time through the loop. It also can't read foo2[i] until the write to barOut...
Counting inversions in an array
...g an algorithm to do the following: Given array A[1... n] , for every i < j , find all inversion pairs such that A[i] > A[j] . I'm using merge sort and copying array A to array B and then comparing the two arrays, but I'm having a difficult time seeing how I can use this to find the number ...
Entity Framework: There is already an open DataReader associated with this Command
...connection correctly. My understanding of this problem is that there are multiple data retrieval commands executed on single connection (or single command with multiple selects) while next DataReader is executed before first one has completed the reading. The only way to avoid the exception is to al...

Is the order guaranteed for the return of keys and values from a LinkedHashMap object?
...shMap, it looks like this:
private final class KeySet extends AbstractSet<K> {...}
public abstract class AbstractSet<E> extends AbstractCollection<E> implements Set<E> {...}
Thus LinkedHashMap/HashMap has its own implementation of Set i.e. KeySet. Thus don't confuse this w...
What is the difference between procedural programming and functional programming? [closed]
...s a generalisation. This property, evaluating a computation when its result is needed rather than sequentially where it’s called, is known as “laziness”. Not all functional languages are actually universally lazy, nor is laziness restricted to functional programming. Rather, the description gi...
