# Help on algorythm

Guys i have been trying to make this algorythm but with no sucess, can
you help me out ?

The problem is the follow

for the following numberset like 1,2,3,4,5,6,7,8,9,10,11,12 i need to
take all the five number combinations, six number combinations and the
seven number combinations, this cant be “hardcoded”, this need to be
flexible because at any time i may need all the 3 number combinations
and later i may need numbersets of 15 or even more.

Need a little help with this guys

Of course, this assumes that one knows the meaning of the English word
Permutations. I’m not sure if this was the case or not with the original
poster, perhaps he wasn’t simply being lazy !
Oh he did not ask for permutations, he asked for combinations, are we
being unfriendly?

Gregory, I can’t believe you’d use some url shortener of questionable
language choices, surely http://rubyurl.com/ltJs is a better option.

Good point he didn’t specifically state that position mattered and did
actually say combination, oh well my bad

The hilarious site Greg used has the other option built-in. We
should lobby them for RubyURL support.

In Ruby 1.8.7

numberset=(1…12).to_a

(5…7).each do |combination_size|
numberset.combination(combination_size).do_something_with_it
end

Indeed I think you made a good point.

No, not at all. I was simply making the observation that selecting the
correct (often English due to the availability of material in that
language) word can open a goldmine of results in Google searches.
Sometimes all one can do is explain a concept, because one doesn’t have
the vocabulary to reduce it to a single, searchable word.

At least, that’s been my experience with the non-native languages I
speak poorly, and I’m counting mathematics as one of those languages
here!
