URL shortner implementation in C. This is just an example how it could be implemented. Ideally the lookup table should be pre-generated and not hardcoded.

| * This url-shortner it only works with ASCII characters. It encodes and | |
| * decodes ids. | |
| * You can change base_x as you wish. | |
| * | |
| * It runs at least 20 times faster then a Python implementation. | |
