To pop the first element in the list, use the RemoveAt() method. It eliminates the element from the position you want to remove the element.Set the listList myList = new List() { "Operating System", "Computer Networks", "Compiler Design" };Now pop the first element using RemoveAt(0)myList.RemoveAt(0);Let us see the complete example.Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { List myList = new List() { "Operating System", "Computer Networks", "Compiler Design" }; ...

Handshaking is an I/O control approach to synchronize I/O devices with the microprocessor. As several I/O devices accept or release data at a much lower cost than the microprocessor, this technique is used to control the microprocessor to operate with an I/O device at the I/O devices data transfer rate.The drawback of the strobe approach is that the source unit that starts the transfer has no method of knowing whether the destination unit has received the data element that was located in the bus. A destination unit that initiates the transfer has no method of knowing whether the source unit ... Read More
A tensor in PyTorch can be normalized using the normalize() function provided in the torch.nn.functional module. This is a non-linear activation function.It performs Lp normalization of a given tensor over a specified dimension.It returns a tensor of normalized value of the elements of original tensor.A 1D tensor can be normalized over dimension 0, whereas a 2D tensor can be normalized over both dimensions 0 and 1, i.e., column-wise or row-wise.An n-dimensional tensor can be normalized over dimensions (0, 1, 2, ..., n-1).Syntaxtorch.nn.functional.normalize(input, p=2.0, dim = 1)ParametersInput – Input tensorp – Power (exponent) value in norm formulationdim – Dimension over which ...

There are multiple ways by which we can add packages to our existing anaconda environment.Method 1 − One common approach is to use the “Anaconda Navigator” to add packages to our anaconda environment. Once “Ananconda Navigator” is opened, home page will look something like −Go to Environments tab just below the Home tab and from there we can check what all packages are installed and what is not.It is very easy to install any package through anaconda navigator, simply search the required package, select package and click on apply to install it. Let's suppose tensorflow packages are not installed in ... Read More
We may need to perform action on an element which is not present in the viewable area of the page. We need to scroll down to the page in order to reach that element.Selenium cannot perform scrolling action directly. This can be achieved with the help of Javascript Executor and Actions class in Selenium. DOM can work on all elements on the web page with the help of Javascript.Selenium can execute commands in Javascript with the help of the execute_script() method. For the Javascript solution, we have to pass true value to the method scrollIntoView() to identify the object below ... Read More
To change the text font family in HTML, use the style attribute. The style attribute specifies an inline style for an element. The attribute is used with the HTML tag, with the CSS property font-family. HTML5 do not support the tag, so the CSS style is used to add font size.Just keep in mind, the usage of style attribute overrides any style set globally. It will override any style set in the HTML tag or external style sheet.ExampleYou can try to run the following code to change the text font family in an HTML pageLive Demo ... Read More
TCP/IP signifies the transmission control protocol/Internet Protocol. It was created by the Defence Advanced Research Projects Agency (ARPA, later DARPA) in the late 1970s.It is a collection of communication protocol. Moreover, it involves collection and methods for managing packet transport, media access, session interaction, data transfer, email and terminal emulation.Advantages of TCP/IP ModelThe main advantages of TCP/IP are as follows −It is a broadly accepted model which can deploy effectively in all the practical networking issues.TCP / IP can also enable cross-platform communications among the heterogeneous networks.It supports connection-oriented reliable service. It defines that it maintains the transfer of data ... Read More
In object oriented programming, both constructor and destructor are the member functions of a class having the same name as the class. A constructor helps in initialization of an object, i.e., it allocates memory to an object. On the other hand, a destructor deletes the created constructor when it is of no use which means it deallocates the memory of an object. In this article, we will discuss the important differences between constructors and destructors. Let's start with some basic concepts of constructors and destructors. What is a Constructor? A constructor is a member function of a class that initializes ... Read More
There are several methods to check that string is an int or not and one of those method is to use isdigit() to check the string.Here is an example to check whether a string is an int or not in C++ language,Example Live Demo#include #include using namespace std; int main() { char str[] = "3257fg"; for (int i = 0; i < strlen(str); i++) { if(isdigit(str[i])) cout
