题目Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree [1,null,2,3], return [1,3,2]. Note: Recursive solution is trivial, could you do it iter…

Insertion sort works the best and can be completed in fewer passes if the array is partially sorted. But as the list grows bigger, its performance decreases. Another advantage of Insertion sort is that it is a Stable sort which means it maintains the order of equal elements in the list. ...
Document order is defined as the order of the structural elements in the serialized document or, in other words, the depth-first traversal of the document's logical structure (see Figure 4). Figure 4 Doc Order Running the code fragment shown previously against the following XML document...
