The standard library in Java had a subtle bug in their implementation of binary search, which remained undiscovered for a decade! But the bug itself traces its roots much earlier than that. Note: I once fell victim to the binary search algorithm during a technical screening. There were a ...
In the binary search tree, each node is placed such that the node is always larger than its left child and smaller than equal (in case of duplication) to its right child. This definition recursively applies to every node of the tree. Thus, we always have a root larger than all nodes ...
Java 8 allows us to add non-abstract methods in the interfaces. These methods must be declareddefaultmethods. Default methods were introduced in java 8 to enable the functionality of lambda expression. Default methods enable us to introduce new functionality to the interfaces of our libraries and ...

How to check if an array (unsorted) contains a certain value? This is a very useful and frequently used operation in Java. It is also a top voted question on Stack Overflow. As shown in top voted answers, this can be done in several different ways, but the time complexity could be ve...
Convert (11111)* to base 10. Outline an algorithm to convert decimal numbers to binary in java. Convert 245 and 24 to binary. Using the subtraction rule, compute 24 - 245 in binary. (Hint: you will need to work with more than eight bits; use nine-bit numbers and fixed precision.) ...

of a binary tree in Java, in thefirst part, I have shown you how to solve this problem using recursion and in this part, we'll implement the inorder traversal algorithm without recursion. Now, some of you might argue, why use iteration if the recursive solution is so easy to implement...
