...s what I ended up doing:
I created an (invisible) FrameLayout called touchInterceptor as the last View in the layout so that it overlays everything (edit: you also have to use a RelativeLayout as the parent layout and give the touchInterceptor fill_parent attributes). Then I used it to intercept to...
Finding three elements in an array whose sum is closest to a given number
Given an array of integers, A 1 , A 2 , ..., A n , including negatives and positives, and another integer S. Now we need to find three different integers in the array, whose sum is closest to the given integer S. If there exists more than one solution, any of them is ok.

How can I add reflection to a C++ application?
I'd like to be able to introspect a C++ class for its name, contents (i.e. members and their types) etc. I'm talking native C++ here, not managed C++, which has reflection. I realise C++ supplies some limited information using RTTI. Which additional libraries (or other techniques) could supply this ...
