C#: 0 & 1 Permutations

Question

I want to list permutations with only 0 and 1. Similar to binary but allowing variable lengths, doesn\'t have to equal 8 length. For example:

0
1
00
01
10
11
000         


        

Answer 1

You can also use:

using System;

class Test
{
    static void permute(int len)
    {
        for (int i=1; i<=len; i++) 
        {
            for (int j=0; j

Which involves no recursion :)
