Data Structure

If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. In this program, we will see how to implement stack using Linked List in java. The Stack is an abstract data type that demonstrates Last in first out (LIFO) behavior. We will implement the same behavior using […]

If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. In this post, we will see how to delete a node from binary search tree. There are two parts to it. Search the node After searching that node, delete the node. There are three cases which we […]
