Queues are a fundamental data structure in the field of computer science and are utilized extensively in a variety of applications and algorithms.    This article examines the queue data structure concept and its implementation in the Java programming language.    First-in, first-out (FIFO) is analogous to the sensation of waiting in a physical line or queue. This feature...

Computer Science is one of the subjects where professional coders are creating various technical concepts for everyday life benefits. Take for example a smartphone. Without coding, our smartphones won’t run; this is how important programming is. Speaking of coding, nothing works without an algorithm. Notably, there are plenty of algorithms, each serving its unique purpose.  In this...

You are most likely to encounter string questions in your upcoming tech giant’s coding interview!  From longest palindromic substring to superstring to palindrome partitioning, you will be asked a variety of string related coding questions. One such important string topic that often appears in the coding interviews is finding the first unique characters in a string.  Here, you...

In the modern age, multitasking is all we require to save time as well as money. But, what if we told you that you could multitask while compiling a program? That is certainly possible by using the function of compile time polymorphism. The concept of polymorphism refers to completing several tasks at the same time using the same method. Now, the concept of compile time polymorphism, takes this...

In schools or computer classes you may have often heard of the term, ‘palindrome’! But have you ever thought, you would encounter this concept more than often in your coding journey.  In coding interviews, you may often come across the topic of palindrome string.  A palindrome string is represented as the one that reads the same from left to right and right to left. ...

Programming is a vast concept. From DSA to OOPs, the classes, functions, algorithms and approaches seem to have absolutely no end! That is why, the sheer complexity of coding concepts make it really difficult to cover them all within a course of 2 months before the technical interviews. One such concept that we shall be discussing today is the triplet sum in array. An array consists of triplets...

From Diffie-Hellman Key Exchange to RSA private keys, the use of modular exponentiation in cryptography is endless. The formula for modular arithmetic progression basically provides the key ingredients for the functioning of multiple public crypto-systems. But, since this is an arithmetic progression, the performance of the program is highly affected by multiple layers of calculations and...

If you are a programmer, binary trees are a must learn topic!  Binary Tree Camera problem is a common question raised in most technical round interviews. It’s a relatively tougher problem and presented primarily to experienced candidates. But recent graduates should prepare for this problem as well. Hence, if you want better detailing on this subject you are at the right...

Given an array, you have to find the subarray sum which is divisible by K.  The Subarray problems are being asked in a lot of coding contests and interviews. For solving the problem, you will require to have the basic concept of the Linear data structure and its working. If you are not good at that, then it will be going to be difficult for you to solve this question. We are here with the...
