Why doesn't C++ have a garbage collector?
...is very powerful and allows you to do almost anything. For this reason it doesn't automatically push many things onto you that might impact performance. Garbage collection can be easily implemented with smart pointers (objects that wrap pointers with a reference count, which auto delete themselve...
What are unit tests, integration tests, smoke tests, and regression tests?
...t check that when the system under test is invoked it returns normally and does not blow up.
Smoke testing is both an analogy with electronics, where the first test occurs when powering up a circuit (if it smokes, it's bad!)...

private func realFunction // (a,b) -> c
get(a, b)
{
c result;
map<a,c> endCache;
if (cache[b]...

List comprehension: Returning two (or more) items for each item
...
This is better than my sum(..., []) answer because it does not require recreating the list on every + (thus has O(N) performance rather than O(N^2) performance). I'll still use sum(..., []) when I want a quick one-liner or I'm in a hurry, or when the number of terms being combin...
