The are a number of examples of AVL rotations in books and on the internet, but what I discovered appeared arbitrary and nobody position gave the impression to include simple examples for all 4 instances for insert and delete.

These are the most straightforward test case I may get a hold of for the 4 forms of rotations. To make it easy to describe, I've used ascii characters as the key so a test case can be expressed as a string. For example, the string "abc" could be insert "a", insert "b" after which insert "c".

The full take a look at circumstances create some pretty difficult trees so I've created two take a look at suites. The first causes the rotations, however has empty sub-trees for the nodes being turned around making it easy to see what actually came about. The second suite has non-empty sub-trees to fully take a look at the rotation code.

There seem to be two different nomanclature for rotates - what I realized as a 2L rotation, some books name an rl rotation and the 2R rotation is name an lr rotation. The text underneath uses 2R/2L.

These are the easy take a look at cases for insert

"abc", on the insert of "c" would require a 1L rotation

a b \ / \ b == 1L ==> a c \ c

"cba", on the insert of "a" would require a 1R rotation

c b / / \ b == 1R ==> a c / a

"acb" on the insert of "b" would require a 2L rotation

a b \ / \ c == 2L ==> a c / b

"cab" on the insert of "b" will require a 2R rotation

c b / / \ a == 2R ==> a c \ b

For delete

"bcad", on the deletion of "a" would require a 1L rotation

b c x \ / \ a c == 1L ==> b d \ d

"cbda", on the deletion of "d" would require a 1R rotation

c b / x / \ b d == 1R ==> a c / a

"bdac" on the deletion of "a" would require a 2L rotation

b c x \ / \ a d == 2L ==> b d / c

"cadb" on the deletion of "d" will require a 2R rotation

c b / x / \ a d == 2R ==> a c \ b

The extra advanced check circumstances have sub-trees, most simply being a unmarried node. To make this submit shorter, the insert and delete check circumstances are blended. The delete example becomes the insert instance by way of skipping the insertion of the delete character. For instance, the usage of the 2R easy delete case above "cadb" turns into the insert case "cab" by way of skipping the insert of "d". One end result of this is the double rotate circumstances below require putting an additional node to stay the tree balanced after inserting the node to be deleted. This leads to the insert case not being minimal.

"cbedfag" on the delete of "a" or skipping "a" and the insert of "g" will require a 1L rotation at c

c e / \ / \ b e == 1R ==> c f x / \ / \ \ a d f b d g \ g

"ecfbdga" on the delete of "g" or skipping "g" and the insert of "a" will require a 1R rotation at e

- e - c / \ / \ c f == 1R ==> b e / \ x / / \ b d g a d f / a

"ecjadhkgilbf" on the delete of "b" or skipping "b" and the insert of "f" would require a 2L rotation at j then e. The insert case can optionally skip putting "d".

- e - —- h —- / \ / \ c j - e- j / \ / \ == 2L ==> / \ / \ a d h k c g i ok x / \ \ / \ / \ b g i l a d f l / f

"hckbeiladfjg" on the delete of "j" or skipping "j" and the insert of "g" will require a 2R rotation at c then b. The insert case can optionally skip inserting "l"

- h - - e - / \ / \ c okay c - h - / \ / \ == 2R ==> / \ / \ b e i l b d f ok / / \ x / \ / \ a d f j a g i l \ g

Use strategies 1 and a couple of from the question to ensure the tree rebalanced as required (ie, verify tree is still so as and balanced). If you wanted to be truly sure, convert the visual test instances to include a listing of intensity and balance values of the overall tree to verify right through an inorder traversal.
