Palindrome by swapping only one character
In a C++ environment, the palindrome is a process where a set or string remains same from the intial stage of the process to termination of that same particular process. Assume, we have a string denoted as the str[]. And the task is to check the string will be paindrome or not after performing the swapping process with only one character for once. Here is a general example of the swapping process − Input : ARBRDD Output : true Explanation: Swap the value A(1st index present in the list) with the R. Input : INDBAN Output : true Explanation: ...
Read MorePrint reverse string after removing vowels
The reverse() is a pre-installed and predefined header file, which is used to define as a template in a process in a C++ environment. The method is able to reverse the elements from last to first manner in a range for any value container. For this process the time complexity is O(n). Lets assume, we have a string or a sentance declared as str[] with some data elements and now the task is to perform reverse process after removing the vowels from that string to get the final outcome. Here is some general examples of the process method − ...

The reverse() is a pre-installed and predefined header file, which is used to define as a template in a process in a C++ environment. The method is able to reverse the elements from last to first manner in a range for any value container. For this process the time complexity is O(n). Lets assume, we have a string declared as str[] with some data elements and now the task is to perform reverse process on this string to get the final outcome. Here is a general example of the process − Input string is here : S = "ARBRDD" ...
Read MoreCount palindromic characteristics of a String
In a C++ environment, the palindrome is a characteristics where we get the same value after getting the result. Assume, there is a string denoted as S and the length is N. Now we need to run an operation on that string to find the palindromic characteristic is the number of k-palindromes in a given range. Here is a general example of the process − Input for the process : abba Output by the process : 6 1 0 0 Explanation of the method: "6" 1-palindromes numbers operation = "a", "b", "b", "a", "bb", "abba". "1" 2-palindromes numbers operation ...
Read MoreWhat is the use of the \'&\' symbol in C++?
The & symbol is used as an operator in C++. It is used in 2 different places, one as a bitwise and operator and one as a pointer address of operator.Bitwise ANDThe bitwise AND operator (&) compares each bit of the first operand to that bit of the second operand. If both bits are 1, the bit is set to 1. Otherwise, the bit is set to 0. Both operands to the bitwise AND operator must be of integral types. Example #include using namespace std; int main() { unsigned short a = 0x5555; // pattern 0101 ... unsigned short b = 0xAAAA; // pattern 1010 ... cout
Read MoreDjango CRUD (Create, Retrieve, Update, Delete) Function Based Views
CRUD is abbreviated as Create, Retrieve, Update and Delete Functions. In Django, we can perform all these CRUD operations on the data we created into the database. Now let’s create the views.py function based on the operation that we want to perform. Create Operation with Django Create is used to create or add new data entries to the database table. In the following snippet, we begin by importing both the model form and the corresponding model. Next, we proceed to check whether the request is a POST request. If it is a POST request, we create a new form ...
Read MoreDjango form field custom widgets
A widget is the representation of the Html input element using Django. The widget is used to handle the rendering of the HTML page and data extracting from the POST/GET dictionary. Every time whenever we specify the field on a form, Django uses the default widget to display the data in an appropriate manner. Django is the one of the best Framework used by most of the users, to perform the web development. It provides many advanced features, functions and packages to design the best web pages and connect with the servers using the python programming language. Now let’s ...
Read MoreDjango Form submission without Page Reload
In Django, we can submit the form without reloading the page using the Jquery and Ajax (Asynchronous JavaScript and XML) requests. Let’s see an example to work with the Ajax to submit the Django form without reloading the page. Create a new Django project First create a new project in Django with the name Reload_project and also create a new app in the project directory with the name Reloadapp by executing the below commands in the command prompt. django-admin startproject Reload_project cd Reload_project django-admin startapp Reloadapp Now in INCLUDED_APPS in settings.py file of the Reload_project directory, add the ...
Read MoreHow to move a Torch Tensor from CPU to GPU and vice versa?
A torch tensor defined on CPU can be moved to GPU and vice versa. For high-dimensional tensor computation, the GPU utilizes the power of parallel computing to reduce the compute time.High-dimensional tensors such as images are highly computation-intensive and takes too much time if run over the CPU. So, we need to move such tensors to GPU.SyntaxTo move a torch tensor from CPU to GPU, following syntax/es are used −Tensor.to("cuda:0") or Tensor.to(cuda)And, Tensor.cuda()To move a torch tensor from GPU to CPU, the following syntax/es are used −Tensor.to("cpu")And, Tensor.cpu()Let's take a couple of examples to demonstrate how a tensor can be ...
Read MoreXOR Linked List – A Memory Efficient Doubly Linked List
Linked List The linked list is a linear data structure containing elements called nodes. Each node consists of two main components: data (payload of that node) and a pointer to the next node in the list. They are simple and efficient to use providing easy allocation and deallocation of memory. Doubly Linked List Doubly linked list is a special type of linked list which again consists of a basic element called nodes. Each node consists of three main components: data (payload of that node), a pointer to the previous node of the sequence and a pointer to the next ...
