The Balanced Factor is calculated as follows: balancedFactor = height(left subtree) - height(right subtree). If the balance factor remains -1,0, or +1, then no rotations are necessary. However, if balance factor becomes less than -1, or greater than +1, the subtree rooted at this node is unbalanced. If insertions are performed serially, after each insertion, at most one of the following cases needs to be resolved to restore the entire tree to the rules of AVL. -wikichrrylylbrcs
