WebJul 6, 2015 · Let's say that you want to delete 8. You try to find largestValue from nodeToRemove.Left. This gives you 7 since the left sub-tree only has one child. Then you do: nodeToRemove.Value <- largestValue.Value Which means: 8.value <- 7.Value or 8.Value <- 7 So now your tree looks like this: 7 / \ 7 9 WebIf you are making a backtracking algorithm where going back to a previous tree is needed #1 is the only choice and it will share as much structure with the previous version of the tree. If you want to iterate and update a data structure to reflect something where you never need th eprevious state #2 is the best choice.

"WebA binary search tree (BST) is a data structure in which each node has at most two child nodes, left and right. The left child node holds a value less than or equal to its parent node, and the right child node holds a value greater than the parent node.

WebInserting into a binary search tree. To insert a value, just find where that value would have been, had it already been in the tree, then add the value as a new leaf. For example, inserting 13 as shown below would result in the following change. The actual insertion takes place when a null tree is encountered.
