Removal In a normal binary tree search, when you delete an internal node with two nodes as children, we take the maximum element of the left subtree or the minimum of the right subtree, and move its value at that node is removed (as shown here). Then remove the node from which copiabamos the value must be less than two leaves no child nodes. Copy a value does not violate any of the red-black properties and reduces the problem of general andalusia delete to delete a node with at most one leaf child. No matter if this node is the node that originally we wanted to delete the node or the value of that copy. Summarizing, we can assume that we remove a node with a child as much leaf (if leaf nodes only have children, take them as a child). If you remove a red node, we can simply replace it with your child, to be black. All roads to simply delete the node pass through a node less red, and both nodes, the father of the deletion and the child have to be black, so that the properties 3 (all pages, including zero, are black ) and 4 (the two sons of every red node are black) are maintained. Another simple case is when the deleted node is black and his son is red. Simply remove a black node could break the 4 properties (the two children of every red node are black) and 5 (all paths from a given node to its leaves contain the same number of black nodes), but if your child repainted in black Both properties are preserved. The complex case is when the node that will be erased and his son are black. We started by replacing the node that will be wiped off...
