Efficient way to return a std::vector in c++
...gnment is optimized by something different, called "move semantics". In C++03, the above code does cause a copy, and although in theory an optimizer might be able to avoid it, in practice its too difficult. So instead of myvec = f(), in C++03 you should write this:
std::vector<int> myvec;

Convert HH:MM:SS string to seconds only in javascript
...

'01:02:03'.split(':').reduce((acc,time) => (60 * acc) + +time);
This is because each unit of time within the hours, minutes and seconds is a multiple of 60 greater than the smaller unit. Time is split into hour minutes and sec...
