When we put those numbers in a binary search tree, we only need average(1 + 2 + 2 + 3 + 3 + 3 + 3) / 7 = 2.42 comparisons to find the number. The Binary Search Tree 's search algorithm is roughly O(log2n) However this is the best-case . ...
node.right = null; return node; } Time Complexity of BST operations is O(h). h is the height of the tree. That brings an end to this tutorial. You can checkout complete code and more DS & Algorithm examples from ourGitHub Repository....
注意了:_insertR这里第一个参数我们用的引用,如果不用引用的话,那么root就只是一个拷贝,并不会对实际的二叉树产生影响。下面是删除函数的递归形式 那如果我们想用一棵二叉树生成另一颗二叉树,我们就要写拷贝构造,因为默认生成的是浅拷贝,以及后面一系列的析构和赋值重载 ...
Algorithm: If node == NULLreturncreateNode(data)if(data< node->data) node->left = insert(node->left,data);elseif(data> node->data) node->right = insert(node->right,data);returnnode; The algorithm isn't as simple as it looks. Let's try to visualize how we add a number to an ...
