// we will use weak references with the Rc<T> (reference counting pointer) type
// weak references allow us to make references to a value that will -not- keep it alive
// this is perfect in the intsance of children, as we will soon see
use std::rc::{Rc,Weak};

use std::cell::RefCell;
// this example builds upon the last by storing a vector of children as well as a parent

// Suppose we have a permutation containing N different elements. 
// Heap found a systematic method for choosing at each step a pair of elements to switch, 
// in order to produce every possible permutation of these elements exactly once. 
// Let us describe Heap's method in a recursive way. First we set a counter i  to 0. 
// Now we perform the following steps repeatedly until i  is equal to N. 
// We use the algorithm to generate the (N − 1)! permutations of the first N − 1 elements, 
// adjoining the last element to each of these. This generates all of the permutations that 
// end with the last element. Then if N is odd, we switch the first element and the last one, 
// while if N is even we can switch the i th element and the last one (there is no difference between 
// N even and odd in the first iteration). We add one to the counter i and repeat. In each iteration,
