Topic:Given a binary tree, return the bottom-up level order traversal of its nodes ' values. (ie, from the left-to-right, the level by level from the leaf to root).For example:Given binary Tree [3,9,20,null,null,15,7] , 3 / 9 / 7Return its bottom-up level order traversal as:[ [15,7], [9,20], [3]]test instructions and analysis: gives the result of a binary tree breadth traversal, from the leaf node to the root node. Similar to the previous root node to the leaf node, only the resul

Could you devise a constant space solution?test instructions and analysis: two point order of a binary search tree is wrong, restore it. to find two points of the sequential exchange, the exchange point is a couple of situations: (1) One is the adjacent two points exchange, so that only one reverse order (2) is not adjace

So how exactly does unity support the Oculus VR operation. First, let's look at how the unity scene is built. In the Unity Integration Development package There is a camera preset, which provides the most basic VR technology, including: Oculus Stereo rendering and head tracking, let's take a concrete action.

In an extended version of the game Lights out, are a puzzle with 5 rows of 6 buttons each (the actual puzzle has 5 rows of 5 buttons each). Each button has a light. When a button is pressed, which button and each of it (up to four) neighbors above, below, right and left, has the state O F its light reversed. (If on, the light are turned off; if out, the light is turned on.) Buttons in the
