Doing permutation of different arrays in perl
- by nubie2
Hello!
I want to do permutation in perl. For example I have three arrays. ["big", "tiny", "small"] and then I have ["red", "yellow", "green"] and also ["apple", "pear", "banana"].
How do I get:
["big", "red", "apple"]
["big", "red", "pear"]
..etc..
["small", "green", "banana"]
I understand this is called permutation. But I am not sure how to do it. Also I don't know how many arrays I can have. There may be three or four, so I don't want to do nested loop.
