I am trying to make a class to build a simple tree. If we have a root as item #1, the next item added (#2) would be its left child. The next item added (#3) would be placed as the right child. The method would sense there are out of options and to go to the far left and use the next depth: Item #4 would be the left child of item #2 and item #5 would be the right child of #2 as well. This would just keep continuing as items are added. What type of steps would it take to do this?
