The [[parse tree|parse graph]]s that we've been looking at so far are one step toward the [[data structure|pointer graphs]] that it takes to make trees live in computer memory, but they are still a couple of steps too abstract to properly suggest in much concrete detail the species of dynamic data structures that we need. The time has come to flesh out the skeleton that we've drawn up to this point. | The [[parse tree|parse graph]]s that we've been looking at so far are one step toward the [[data structure|pointer graphs]] that it takes to make trees live in computer memory, but they are still a couple of steps too abstract to properly suggest in much concrete detail the species of dynamic data structures that we need.
