#Info
The goal of this library is to find all possible variations of any data array. For example if you want to know all variations of 3 elements each of which can take the value from 0-2.
Just fill input data
List<List<Integer>> allPossibleVariations = new ArrayList<>();
for (int i = 0; i < 5; ++i) {
List<Integer> variation = new ArrayList<>();
for (int j = 0; j < 10; ++j) {
variation.add(j);
}
allPossibleVariations.add(variation);
}
then pass it to getAllVariations method
Variation<Integer> variation = new Variation<>();
Set<List<Integer>> result = variation.getAllVariations(allPossibleVariations);
and you will get the result:
0 0 0
0 0 1
0 0 2
0 1 0
0 1 1
0 1 2
0 2 0
0 2 1
0 2 2
1 0 0
1 0 1
1 0 2
1 1 0
1 1 1
1 1 2
1 2 0
1 2 1
1 2 2
2 0 0
2 0 1
2 0 2
2 1 0
2 1 1
2 1 2
2 2 0
2 2 1
2 2 2
This library can cope with any size of input data. The only limitation is your computing power ;)
