);Solution 3: Improved on the basis of solution 2, because each time it is from the root node to compare, it will take a little more time, and then we will use a stack to save the root node, the root node of the right sub-tree nodes (bottom of the root node) .... Since the inserted a is the largest, it must first be compared to the right, 1. If insert.b (2) Insert ();Solution: First according to the nature of the binary sorting tree, according to the size of a is inserted into a leaf node, after
