Test item2 = new Test();
Test.TTT = "1";
What are the values?
Well
in item1 TTT = 1 and somedata = 200

Algorithm to generate all possible permutations of a list?
Say I have a list of n elements, I know there are n! possible ways to order these elements. What is an algorithm to generate all possible orderings of this list? Example, I have list [a, b, c]. The algorithm would return [[a, b, c], [a, c, b,], [b, a, c], [b, c, a], [c, a, b], [c, b, a]].
