Introduction Graph traversal could be a principal operation in computer science that includes going by all nodes of a graph. In certain scenarios, it may be fundamental to navigate the graph in the lexicographical order of nodes, which suggests going by the nodes in climbing numerical order. In this article, we'll investigate two distinctive approaches to performing a lexicographical DFS traversal of a graph utilizing the C language. These approaches point to creating the same correct yield while giving elective executions and viewpoints. They offer an establishment for understanding a wide extent of graph-related issues, empowering productive investigation, and analysis ... Read More
Introduction Finding the smallest set of vertices to visit all nodes in a graph could be a crucial issue in graph hypothesis. It has practical applications in different areas, counting network optimization, directing algorithms, and task planning. In this article, we are going investigate three diverse approaches to illuminate this problem: Depth-First Search (DFS), Breadth-First Search (BFS), and Depth-First Traversal with Backtracking. We are going give point by point clarifications, code usage within the C language, and algorithmic steps for each approach. Also, we'll illustrate the utilization of these approaches with a test graph to guarantee that all three strategies ... Read More
Introduction The number of ways to reach the beginning hub after traveling through precisely K edges in a total chart can be calculated utilizing different approaches within the C dialect. One approach is to utilize brute constrain recursion, where we investigate all conceivable ways. Another approach includes energetic programming, where we store and reuse halfway comes about to dodge excess computations. Moreover, a numerical equation exists to specifically compute the number of ways based on the number of hubs and edges. These strategies give effective arrangements to decide the check of ways driving back to the beginning hub in a ... Read More
Introduction Finding the primary undeleted integer from a given extend in a detached graph after performing multiple queries may be a challenging issue in graph theory. In this article, we investigate the errand of distinguishing the primary undeleted numbers and give two approaches to fathom it utilizing C++. Each approach offers a diverse point of view and utilizes distinctive calculations and data structures. The problem includes developing a graph, checking certain nodes as deleted, and after that deciding the primary undeleted numbers inside an indicated extend. The graph represents associations between nodes, and the deleted nodes are those that have ... Read More
In this article, we will learn about the solution to the problem statement given below.Problem statement − We are given a string we need to count the number of words in the stringApproach 1 − Using split() functionThe split() function breaks the string into a list iterable with space as a delimiter. if the split() function is used without specifying the delimiter space is allocated as a default delimiter.Example Live Demotest_string = "Tutorials point is a learning platform" #original string print ("The original string is : " + test_string) # using split() function res = len(test_string.split()) # total no of words print ...

To label a line in matplotlib, we can use label in the argument of plot() method,StepsSet the figure size and adjust the padding between and around the subplots.Plot with label="line1" using plot() method.Plot with label="line2" using plot() method.To place a legend on the figure, use legend() method.To display the figure, use show() method.Examplefrom matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True line1, = plt.plot([1, 2, 3], label="line1") line2, = plt.plot([3, 2, 1], label="line2") leg = plt.legend(loc='upper center') plt.show()Output
In this article, we will show you how to convert date and time with different timezones in Python. Using astimezone() function Using datetime.now() function The easiest way in Python date and time to handle timezones is to use the pytz module. This library allows accurate and cross−platform timezone calculations. pytz brings the Olson tz database into Python. It also solves the issue of ambiguous times at the end of daylight saving time, which you can read more about in the Python Library Reference (datetime.tzinfo) Before you use it you'll need to install it using − pip install pytz ...

We can apply a mask to an image by computing the cv2.bitwise_and() between the mask and the image. To track a color, we define a mask in HSV color space using cv2.inRange() passing lower and upper limits of color values in HSV.Also Read: Color Identification in Images using Python and OpenCV To track a part of the image we can define a mask using np.zeros() and slicing the entries with white (255) for the region in the input image to examine. Follow the given steps to mask an image − The first step is to import required libraries. The ... Read More
Dataframe is a 2D data structure. Dataframe is used to represent data in tabular format in rows and columns. It is like a spreadsheet or a sql table. Dataframe is a Pandas object.To create a dataframe, we need to import pandas. Dataframe can be created using dataframe() function. The dataframe() takes one or two parameters. The first one is the data which is to be filled in the dataframe table. The data can be in form of list of lists or dictionary of lists. In case of list of lists data, the second parameter is the columns name.Create dataframe from ... Read More
In this article we will discuss how to find the number of days between two dates using Python. We use the datetime module to calculate the number of days between two dates using python. datetime module Python has a built-in datetime module that assists us in resolving a number of date-related issues. We just input the two dates with the date type and subtract them to discover the difference between the two dates, which gives us the number of days between the two dates. Syntax The syntax of the date() method in datetime module is as follows. datetime.date(year, month, day) ... Read More
