how to calculate binary search complexity
...f size n will not exceed log n.
This is just formal mathematical lingo in order to be able to prove statements, etc. It has a very straightforward explanation. When n grows very large, the log n function will out-grow the time it takes to execute the function. The size of the "input set", n, is jus...

In this case you should decide whether or not your results require list semantics such as order based indexing (then use IList<T>) or whether you just need to return an unordered "bag" of results (t...
What is a “cache-friendly” code?
... algorithm design
Whenever possible, try to adapt your data structures and order of computations in a way that allows maximum use of the cache. A common technique in this regard is cache blocking (Archive.org version), which is of extreme importance in high-performance computing (cfr. for example AT...
