Here is a program i want ot code with Flex:
I have a text from which I want to extract trigrams.
For example: if I got the two words "Hello world", I would like Flex
to recognize the following sequences:
"Hel", "ell", "llo", "wor", "orl", "rld"
I know i have to use the `reject' clause but i can't get it to work
Maybe you can help me ?
