Difference between Proxy and Decorator Pattern in Java
Hello guys, if you have gone through a couple of Java Developer interview then you may seen this question about Proxy and Decorator Pattern in Java. Earlier, I have share 18 Design Pattern questions and today, I am going to answer this tricky design pattern questions from Java interviews. I was first asked about difference between Proxy and Design Pattern in Java a couple of years back when I was interviewing for Senior Java developer interview on a big investment Bank and I wasn't able to impress interviewer with my answer, so I decided to learn more and this article is the result of that research. Though both Proxy and Decorator pattern looks very similar to each other structurally, there are some key differences between them like what problem them solve and how they are used in Java application.

How to find Kth Smallest Element in a Binary Search Tree? [Solved]
Hello guys, I have been sharing binary search tree-based coding interview questions for quite some time. In the last article, we looked at how to find the maximum sum level in a given binary tree, and in this article, we will find the kth smallest number in a given binary tree like the 5th smallest or 3rd smallest number. Before we find the kth smallest in a Binary search tree, We need to understand
the binary search tree. A Binary tree is a data structure in which each node
can have at most two children. That is, each node in the binary tree will have
data, left child and right child. The first node of the tree is called the
Root.
