Flatten nested dictionaries, compressing keys
...does the key-reducer function (which I hereby refer to as 'join') require access to the entire key-path, or can it just do O(1) work at every node in the tree? If you want to be able to say joinedKey = '_'.join(*keys), that will cost you O(N^2) running time. However if you're willing to say nextKey ...
What is the difference between map and flatMap and a good use case for each?
...g from a collection of lines to a collection of words looks like:

The input and output RDDs will therefore typically be of different sizes for flatMap.
If we had tried to use map with our split function, we'd h...

What does 'const static' mean in C and C++?
...p;i' then the address will be different for each translation unit.
// foo.cc
static const int i = 0;
'i' has internal linkage, and so cannot be referred to from outside of this translation unit. However, again unless you use its address it will most likely be treated as a type-safe 0.
