+Example 1:
+Question: There is a dismantling engineer who has old machines A, B, and C.
+He discovered that he can obtain a batch of new parts X, Y, Z through the following rules:
+1. One unit of machine A can be dismanteled into two units of part X and one unit of part Y.
+2. Two units of machine B can be dismanteled into one unit of part X.
+3. Two units of machine C can be dismanteled into one unit of part Y.
+4. One unit of machine B and one unit of machine C can be combined into one unit of machine A.
+5. One unit of part X and one unit of part Y can be combined into one unit of part Z.
+
+Given a certain number of initial machines, your job is to continuously cycle through the rules 1-5 above, exausting one rule at a time, until no more rules can be applied, or until a state (counts of each machine and part type) is repeated.
+After you make use of a rule, you should update the counts of each machine and part type accordingly, and then restart the process from rule 1.
+
+The output should be the count of each machine and part type after the rules have been exhaustively applied in the following order: A B C X Y Z.
+For example 1 0 1 5 4 3 means that you have 1 machine A, 0 machine B, 1 machine C, 5 part X, 4 part Y, and 3 part Z.

+Example:

+- Output: 0 0 1 2 0 2
+- Explanation
+    0. Initial state: 2 0 1 0 0 0
+    1. We can apply rule 1 and trade 1 machine A for 2 part X and 1 part Y: 1 0 1 2 1 0
+    2. Starting over, we can apply rule 1 again: 0 0 1 4 2 0
+    3. In the next iteration, we can apply rule 5 and trade 1 part X and 1 part Y for 1 part Z: 0 0 1 3 1 1
+    4. In the next iteration, we can apply rule 5 again: 0 0 1 2 0 2
+    5. We can't apply any more rules, so the final answer is 0 0 1 2 0 2
