You see the point here when we look at how trees get walked through completely. I always tell you that each method ends up touching every single spot just once. That leads straight to time growing in a straight line with the total spots. But you might wonder about extra steps like checking links. It adds nothing big overall because those checks stay fixed per spot.
Perhaps the recursive way you try first feels heavy at first glance. I notice you often forget how the calls stack up yet the visits still total the same count. Now think about going left then root then right in one pass. You cover everything without repeats or skips. Or maybe switching the order to root first changes nothing in total time spent.
Also the stack you build for holding paths stays separate from the counting of visits. I bet you see why space differs but time does not. Then level by level walking uses a line of waiting spots instead. You still process each one exactly once across the whole run. But unbalanced shapes might stretch the line longer without changing the visit total.
You know the constant factors hide in how you fetch the child links. I mean grabbing them costs the same no matter the order picked. Perhaps in big trees the cache effects play a role yet they do not alter the basic count. Now compare that to graphs where extra marks prevent repeats but trees need none. You avoid that overhead entirely here.
Or consider how a full sweep always equals the size no matter if you start from the top or pick another entry. I find it funny how people overthink it sometimes. Then the work per spot stays tiny like just printing or summing values. You finish fast because nothing repeats. But if the tree holds millions the linear growth becomes obvious in practice.
You watch the calls unwind in post order and still hit the same total. I remind myself the unwind phase adds no new visits. Now perhaps threading through the nodes in a custom order keeps the same bound. You gain nothing by clever tricks on time itself. Also the height affects only how deep the calls go not how many happen.
I see you nodding when I say worst cases match average ones here. Then every leaf and branch gets equal attention without bias. But the constant per operation might vary by language used. You test it and notice the difference stays small. Or maybe swapping to iterative versions cuts some overhead yet leaves the main count untouched.
You realize the analysis holds for any shape from skinny to bushy. I always point out the proof comes from induction on the size. Now each subtree sums to its own size and adds up cleanly. You avoid double counting because links point one way. But shared substructures do not appear in plain trees.
Perhaps you wonder about parallel attempts speeding things up. I tell you the visits remain the same even if threads split the work. Then the coordination adds tiny costs that do not scale with size. You still pay linear time overall. Or consider memory access patterns that might slow real runs but not the theoretical bound.
You get why all standard methods share this trait without exception. I mean pre order hits root early but covers the rest identically. Now post order delays the root yet totals match. But level order spreads across layers without changing the sum. You see the pattern repeating across every variant.
