Given an numbers ... E.g. {1,2,3,4}
I need a way to generale all possible combinations and subset of the numbers.
I need to have all subsets (all subsets of 1 element, all subset of 2 elements, all subset of n elements) an of each subset all possible permutations.
I don't have idea
ALL combination!
Is there a quick way?
For example result should be:
1
1 2
1 3
1 4
1 2 3
1 2 4
1 3 4
1 2 3 4
2
2 3
2 4
2 3 4
3
3 4
4
this my code :
for (int i = 0; i < (2^4)-1; i++)
{
for (int j = 0; j < i+1; j++)
{
for (int k = j; k < i; k++)
{
Console.Write(k+1);
}
Console.WriteLine();
}
}

This my output
584


NOTE :This my question in Stackoverflow and not solution Because they think it is duplicate
