Implement a function to check if a binary tree is balanced. For the purpose of this question, a balanced tree is defined to be a tree such that the heights of the two subtrees of any node never differ by more t
but given a node, how to check if it is or not, we should do this: isBalanced(root) = Math.abs(height(root.left) - height(root.right)) < 1 classSolution{publicbooleanisBalanced(TreeNode root){if(root ==null)returntrue;if(Math.abs(height(root.left) - height(root.right)) >1) {...
Balanced binary trees are also known as height-balanced binary trees. Height balanced binary trees can be denoted by HB(k), where k is the difference between heights of left and right subtrees. ‘k’ is known as the balance factor. If for a tree, the balance factor (k) is equal to ...
