In this article we will learn how to design a LRU Cache, understand it’s cache replacement algorithm. We also look at description of LRU Cache with some examples. Then, we look at the implementation of this design in code with their complexity analysis. Caching is a method of organizing data in a faster memory, usually …
In this article we look into the difference between Primary Key and Unique Key Constraints. We will see the description of both along with how to define a schema and create attributes in a table with these constraints. Primary Key A Primary Key is a key attribute or a column which is used to uniquely …
In this article, we see how to print the bottom view of Binary Tree. We discuss our approach to solve this problem and analyze the time and space complexities. It is recommended to first learn Top View Of Binary Tree before proceeding with this problem. A lot of the implementation is based on the Top …
Given a binary tree we have to print top view. We will discuss our approach to solve this problem along with its implementation and code in Java language. We will also analyze the time and space complexity of our implementation. The top view of binary tree means the set of nodes visible when the tree …
In this article, we look into a problem related to binary tree. Given a binary tree, we have to print its Left View. We will see the different methods to solve this problem with their implementations in java. Along with this, we will also look into the time and space complexities of our methods. By …
