iven a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as: a binary tree in which the left and right subtrees of every node differ in height ...

In a binary tree, if the difference between the heights of the left and right subtrees is less than or equal to 1, then it is a balanced binary tree. In test case no. 208 (see picture below), the left ...

Abstract: Zernike radial polynomials (ZRP) play a significant role in application areas such as optics design, imaging systems, and image processing systems. Currently, there are two kinds of ...
