Circular ArrayAn array in which the next element of the last element is the first element of the array is often termed as circular.Obviously, there exists no such mechanism to store data like this, data will still be stored in continuous memory blocks and circular arrays are more like an idea than reality.ProblemWe are required to write a JavaScript function that takes in a circular array of Integers, arr, as the first and the only argument.The function should then construct and return an array that contains the next greater element for each corresponding element of the original array. The Next ... Read More

In this post, we will understand the differences between aggregation and association.AssociationIt can be understood as an organization of people that have a common purpose. It also indicates that they consist of a formal structure. It represents a binary relationship between the two objects that describe some kind of activity.It is a relationship between multiple objects.An example would be how consuming healthy food is related not just to a healthy weight, but to good skin, good hair, strength and being active.Association is a relationship between two classes where one class uses the other class.It is not flexible in natureThis indicates ...

In this post, we will understand the differences between full virtualization and paravirtualizationFull VirtualizationThis process was introduced by IBM in the year 1966. It is considered to be the first software solution for server virtualization. It uses binary translation and a direct approach method.In this, the guest OS is fully isolated using the virtual machine from the virtualization layer and hardware.Examples of full virtualization include Microsoft and Parallels systems.The virtual machine permits the execution of the instructions in addition to running the unmodified OS in a completely isolated method.It is considered to be less secure in comparison to paravirtualization.It uses ...

In this post, we will understand the differences between flood fill algorithm and boundary fill algorithm. They are area-filling algorithms, and they can be differentiated based on whether a random pixel has the region's original colour or not.Flood-fill algorithmIt is also known as seed fill algorithm.It calculates the area that is connected to a given node with respect to a multi-dimensional array.It works by filling up or recolouring a specific area that contains different colours in the inside part, and hence, the boundary of the image.It is represented by a picture that has a neighbourhood which has borders and has ...

In this post, we will understand the differences between 'for' and 'foreach' loops in PHP −The 'for' loopIt is an iterative loop that repeats a set of code till a specified condition is reached. It is used to execute a set of code for a specific number of times. Here, the number of times is the iterator variable.Syntax:for( initialization; condition; increment/decrement ) { // code to iterate and execute }Initialization: It is used to initialize the iterator variables. It also helps execute them one at a time without running the conditional statement at the beginning of the loop's condition.Condition: ... Read More
In this post, we will understand the differences between the greedy algorithm and dynamic programming methods.Greedy algorithmIt is an algorithmic paradigm that builds up on a solution in parts, step by step. The next step is chosen such that it gives the most obvious and immediate benefit.Problems that involve choosing local optimal values will help in choosing the global optimal values/solution to the problem. Such ate the problems associated with greedy algorithm.There is no surety that a greedy algorithm would lead to an optimal solution.An optimal choice is made at every stage of the problem, i.e the local optimal solution.It ...

In this post, we will understand the differences between Prim's and Kruskal's algorithms.Kruskal's algorithm for Mininum Spanning Tree (MST)When a connected and undirected graph is given, a spanning tree of such a graph is the subgraph which is a tree that connects all of the vertices.A single graph can have multiple spanning trees.A minimum spanning tree (MST) (also known as minimum weight spanning tree) for a weighted, connected and undirected graph is a spanning tree that weighs less than or equal to the weight of every other spanning tree.The weight of a spanning tree is determined by adding the weights ...

In this post, we will understand the difference between an object and a class with respect to C++ programming language.Classes in C++It is a building block of code in C++ that helps implement object oriented programming.It is a type that is defined by the user.It holds its own data members and member functions.These data members and member functions can be accessed by creating an instance of the class.They can be used to manipulate the variables and can be used to define property to tell how the objects in a class have to act.It can be understood as a blueprint for ...

Let us first learn about C# and C++ −C# is a general-purpose object-oriented programming language.It is considered as a pure object-oriented programming language.It is pronounced as 'C sharp'.It was developed by Anders Hejlsberg and his team at Microsoft.Memory Management is done automatically by the garbage collector.It is the language's duty to automatically delete the object once its objective is completed.It is windows specific, i.e. it can't be used on all systems.It doesn't support multiple inheritance.The pointers in C# can only be used in the unsafe mode.It is considered as a high-level language.Once the code is compiled, it gets converted into ...
