Test input generation for red-black trees using abstraction

WebWhen we insert a new node to the red-black tree, the first step is to physically insert the node to the given red-black tree, just as we do for regular binary search tree, and color the node to red.

"WebAlgorithm to maintain Red-Black property after deletion. This algorithm is implemented when a black node is deleted because it violates the black depth property of the red-black tree. This violation is corrected by assuming that node x (which is occupying y 's original position) has an extra black. This makes node x neither red nor black. " - Red black tree test cases

WebAug 11, 2024 · 1 Answer Sorted by: 0 I hate to say it but a RB insert is rough, wait til you get to deletion! Argh! If I recall my CS correctly, the root node should always be black and a red node should not have a red node as a child. New nodes should be red. Then after detecting the violation, you rotate the tree and re-color to maintain this invariant.
