We know that the zero does not count as a node, if per se I actually had managed to hit zero in drawing that, the correct answer would be the bottom one there.

我们知道0不能算作一个节点，如果我确实把零点画成了0，那正确的答案应该是下面的那个。

The first item is the XV5Suppress node located at the top of the screen and the MDX timing nodes located at the bottom of the screen.

第一个项目是位于屏幕顶部的XV5Suppress节点，另一个是位于屏幕底部的MDX时间节点。

Results flow from the bottom of the run tree (leaf nodes) to the top (XTree node) where the result is represented in RSAPI (Resultset API) format and can be sent to the report service for rendering.

结果从运行树（叶子节点）流到顶部（XTree 节点），其中结果以 RSAPI (Resultset API) 格式表示，且可被发送到报表服务以供呈现。

The point I wanted to make is that for every node, except the leaves, the leaves are the bottom of a tree in this case, are weird, right, they draw trees where the root is at the top, and the leaves are at the bottom.

你没必要看到整棵树，我想说的重点是,对每个节点来说，除了叶子节点,叶子节点指的是树的最下面的节点，电脑科学家都很奇怪,他们画树的时候根是在最上面的。
