Every Red-Black Tree is an AVL tree (if we ignore colors)?
Expert Solution
Step 1
AVL tree : it is basically a binary search tree where in it can have a balance factor of 1,0 or -1.
Balance factor is calculated as height of left subtree - height of right subtree.
Red black tree: it is also a binary search tree where every node is either red in colour or black in colour. Root node is always black in colour. And any two adjacent nodes should not have red colour. The number of black nodes in all the paths should be same.
