I have 10 words. How can I get all possible combinations of 5 words (n=10, k=5). The order does not matter.
For example: "A", "B", "C", if k=2 (n=3 in this case), it would like AB, BC and AC. Maybe you know some usefull code or example.
P.S. Sorry if I'm not right enough cause I don't know English very good.
