WebMar 29, 2024 · I am studying how to fix the colors on a red-black tree after deleting a black node. Suppose we want to delete the node 2. This is a black node. He will be replaced by his rith child in the RB-DELETE algorithm. Because we removed a black node and the node replacing it is black (all NIL are black) then we enter the loop in RB-DELETE-FIXUP. WebAug 4, 2012 · I have implemented a red black tree, but it doesn't work well. It inserts the nodes not on the correct way. I think it's so because of FixUp. Does anyone know where am i wrong? When i insert (1, 4, 9, 16). at node 16, it sets the root color to red. then it stops. I have debugged it, but i wasn't able to find the error myself.
