Regular vs Context Free Grammars
...
Regular grammar is either right or left linear, whereas context free grammar is basically any combination of terminals and non-terminals. Hence you can see that regular grammar is a subset of context-free grammar.
So for a palindrome for instance, is of the form,

A->someth...
What REALLY happens when you don't free after malloc?
...s static storage and runtime memory are pretty much the same thing, so not freeing might cause the program to take up more storage. (I'm only speculating here.)

Lock-free multi-threading is for real threading experts

Current "lock-free" implementations follow the same pattern most of the time:

But I am no...
