In order to represent a graph in Java using an incidence matrix, a data structure containing the relationships between vertices and edges must be built. The incidence matrix is a 2D array where the rows and columns stand in for the vertices and edges, respectively, and the entries represent the connections between them. If there is a "1" at position (i, j), vertex i is incident on edge j. Although it may need more memory for large graphs, this approach permits efficient graph operations, such as the insertion or removal of edges. Programmers can efficiently construct and manipulate graph structures ... Read More
A cycle graph is a special kind of graph in which each node has precisely two neighbours and is connected to the others in a complete loop. Cycle graphs may be made quickly and easily with Python's Networkx module. A cycle graph is produced by using the 'networkx.cycle_graph()' function and the number of nodes. This diagram is frequently employed in a variety of applications, including the modelling of periodic phenomena, the representation of circular structures, and the analysis of cyclic processes. It is useful in graph theory and many real-world contexts due to its ease of use and capacity to ... Read More
In this article, we will write Go language programs to return the nth number in Fibonacci sequence using dynamic programming. It is a technique used to solve complex problems by breaking them into smaller sub problems. Memoization is the process of storing the output of the function calls in some data structure by which the next time call is made it need not calculate the output again, it can use that value to make the computation which in return lessens the execution time. Syntax func make ([] type, size, capacity) The make function in go language is used to ... Read More
Counting stages of whole numbers up to N framing non-cyclic diagrams requires investigating every single imaginable change and checking assuming they make non-cyclic charts in view of given conditions. The circumstances are probable connected with a coordinated chart structure shaped from the changes, where the shortfall of cycles suggests acyclicity. This issue includes chart hypothesis ideas and can be moved toward through Profundity First Inquiry or Dynamic Programming. While DFS investigates every stage recursively, DP improves the cycle by putting away middle outcomes. The last count of substantial stages demonstrates the number of ways the whole numbers up to N ... Read More
Locking a cell is important. It allows the user to preserve the integrity of certain cells that contain important formulas, data, or formatting. On the other hand, when a cell is unlocked, it means that it can be edited even when the worksheet is locked. This is typically done for cells where you want to allow users to input data or make changes while the rest of the worksheet remains protected. By selectively locking and unlocking cells, the user can control the level of access and editing permissions for different parts of a protected worksheet. Locking specific cells means that ...

The borders in bootstrap is used to add an outline to the HTML elements such as div, tables, etc. These borders helps to make the elements visually distinct. With Bootstrap, we can add borders, remove borders, specify border colors, modify border width, and create rounded borders. In Bootstrap, there are different classes to add, remove or modify borders. Additive Border Classes To add a border to HTML element, we use the following classes − .border − This class will add a border around the element. .border-top − This will add border on top edge of the element. .border-bottom ...

In Excel, performing a lookup to return an active hyperlink can be a useful technique when you want to dynamically generate clickable links based on specific values. Although Excel does not have a direct function for this purpose, you can combine the VLOOKUP or INDEX function with the HYPERLINK function to achieve the desired result. This combination allows you to search for a value, retrieve a corresponding URL or address, and create an active hyperlink that can be clicked to navigate to the associated location. In this article will consider one simple example to learn the process of obtaining ... Read More
In this article, users get information on how to lock cell the width and height from resizing in Excel. The purpose of this article is to ensure that the layout and formatting of the cells remain consistent and fixed, even if the spreadsheet is manipulated by others. Some other benefits of locking and protecting cells included maintaining data integrity, preserving formulas, making collaboration easy, enhancing data security, and providing template protection. After the successful completion of this task, the user will not be able to resize the height and width of the cell. Example 1: To Lock cell width ... Read More
In this article, the user will take deep practical knowledge of how to look for a value and return the cell above or below in Excel. This article will briefly two examples. The first example demonstrates the process of generating the above cell value in Excel by using the user-defined formula, while the second example demonstrates the process of generating the below cell value in an Excel sheet. Consider the below provided detailed stepwise explanation, to understand the process briefly. Example 1: To look up for a value in excel sheet, and returning the cell value above to the ... Read More
A cumulative sum chart, also known as a cumulative line chart or cumulative frequency chart, is a graphical representation that shows the cumulative sum or total of a series of values over time or another dimension. It is commonly used to analyze and visualize the accumulation or progression of data. The cumulative sum chart plots the cumulative values on the y-axis and the corresponding time or another variable on the x-axis. Each data point on the chart represents the sum of all previous values up to a certain point, starting from an initial value. As new data points are added, ... Read More
