The trie example had some issues;
* It did not follow the code convention in CONTRIBUTING.md
* The createTrieNode used an inefficient zeroing method (looping over
the entries) which also does not zero out holes in the structure (e.g.
an alternative would be to use "*node = &(TrieNode){0}", but calloc
does all that anyway
* It used an inefficient and clumsy printArray method
* It used strlen inside the algorithm; this new method could get rid of
any strlen/strnlen usage (inserts/searches could be sanitized by
snprintf)
* This version can allow for a custom mapping function, e.g. if NULL is
a valid separator (say that you want a trie for certain binary
packages)
* The previous version actually contained out-of-bounds array indexing;
there were no checks for out-of-bound indexing and words in the word
list did contain out of bounds words. It's a surprise it was working
so well.
* This version just returns 'int' to allow for error checks (instead of
a printf inside the algorithm), and uses double pointers for return
values (good practice)
* The usage example contained unnecessary mallocs, switched that out for
scanf. The example is just an example after all, in real applications
you'd have better input sanitazion.
