Solution: 1. #1st naive idea is to use inorder traversal, because of the characteristics of binary search tree, when the kth number is visited, #it is the kth smallest value time complexity o(k), worst time com
In the best case, the tree is a balanced BST. The best case time complexity for insertion and search isO(logn). It is the same as the average case time complexity. Worst case scenario In the worst case, we may have to traverse from the root node to the deepest leaf node, which is ...
1/*2This look up is a fast operation because you eliminate the half3the nodes from your search on each iteration by choose to follow the4left or right of the sub-tree. In the worst case, you will know whether5the lookup was successful by the time there is only one node left to6sea...
Compared tohash maps, BSTs have betterworst caseperformance—O(lg(n))O(lg(n))O(lg(n))instead ofO(n)O(n)O(n).But, on averagehash mapsperform better than BSTs (meaningO(1)O(1)O(1)time complexity). BSTs are sorted.Taking a binary search tree and pulling out all of the elements...
The time complexity for searching a BST for a value is O(h)O(h), where hh is the height of the tree.For a BST with most nodes on the right side for example, the height of the tree becomes larger than it needs to be, and the worst case search will take longer. Such trees are...

Leetcode98.Validate_Binary_Search_Tree 对于二叉搜索树的任意一个节点,其值应满足:向上回溯,第一个向左的节点,是其下界;第一个向右的结点,是其上界。 例如: 从‘14’向上回溯,第一个向左的结点是‘13’,第一个向右的结点是‘14’,所以‘14’的位置正确。 那么,我们反过来,从上向下看,就有:左儿子的父...
So the time complexity for constructing the BST is the time of inserting nodes, which results in total time complexity of in the average case, and in the worst case. We’ll name it . For the traversal time complexity, it takes steps equal to the tree size to read and print all the ...
