Enumerating Groups - Algorithm
Suppose I have 6 items, and I want to choose 3 from them. I want to enumerate them all in some order.
Obviously I can do this by hand very easily: ABC ABD ABE ABF ACD ACE ACF ADE ADF AEF BCD BCE BCF BDE BDF BEF CDE CDF CEF DEF But suppose I wanted to programatically generate the nth combination? Any easy way to do this? Group(5) = ACD for this enumeration. I don't care what enumeration is used, as long as it is a proper enumeration. |
