Both Procedural and Non-procedural Languages are widely used in the development of applications and other computer software. Both these types of languages have different approaches on the basis of which we can differentiate them. In this article, we will discuss the important differences between procedural and non-procedural programming languages. Let's start with some basics of procedural and nonprocedural language. What is a Procedural Language? Procedural languages are command-driven or statement-oriented programming languages. A program written using a procedural programming language includes a sequence of statements, and the implementation of each statement generates the interpreter to modify the value of one ...

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 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 ...

We have seen different problems in different sections. There are some other problems which are not categorized. In this section we will see some of the random problems. In this Section We are going to cover. Adding base n numbers Babylonian method to find the square root Factorial of a large number Check if a given point lies inside a Polygon Check Perfect Square or Not Check if given four points form a Square Check if two given sets are disjoint? Check if two line segments intersect Check whether a given point lies inside a Triangle Connect n ropes ... Read More

This algorithm is used to print the array elements in a spiral way. At first starting from the first row, print the whole content and then follow the last column to print, then the last row and so on, thus it prints the elements in spiral fashion. The time complexity of this algorithm is O(MN), M is the number of rows and N is the number of columns.Input and OutputInput: The matrix:  1   2   3   4   5   6  7   8   9  10  11  12 13  14  15  16  17  18 Output: Contents of ...

This algorithm will take an array and shuffle the contents of the array. It will generate a random permutation of the array elements.To solve this problem, we will swap elements starting from the last index to randomly generated an index in the array.Input and OutputInput: An array of integers: {1, 2, 3, 4, 5, 6, 7, 8} Output: Shuffle of array contents: 3 4 7 2 6 1 5 8 (Output may differ for next run)AlgorithmrandomArr(array, n)Input: The array, number of elements.Output: Shuffle the contents of the array.Begin    for i := n – 1 down to 1, do   ...

The magic square is a square matrix, whose order is odd and where the sum of the elements for each row or each column or each diagonal is same. The sum of each row or each column or each diagonal can be found using this formula. n(n2+ 1)/2Here are the rules to construct a magic square −We will start from the middle column of the first row, of the matrix, and always go to the top left corner to place next numberIf the row exceeds, or the row is not in the matrix, then, change the column as left column and ...
