WebThe binary search tree insert operation is conducted in the first phase. Because a red-black tree is balanced, the BST insert operation is O (height of tree), which is O (log n). The new node is then colored red in the second stage. This step is O (1) since it only involves changing the value of one node's color field. http://www.codebaoku.com/it-java/it-java-yisu-787143.html
