In this tutorial, we are going to learn how to delete all prime nodes from a singly linked list.Let's see the steps to solve the problem.Write struct with data and next pointer.Write a function to insert the node into the singly linked list.Initialize the singly linked list with dummy data.Iterate over the singly linked list. Find whether the current node data is prime or not.If the current data is prime, then delete the node.Write a function to delete the node. Consider the following three cases while deleting the node.If the node is head node, then move the head to next ... Read More

In this tutorial, we are going to learn how to delete a node in doubly linked list.Let's see the steps to solve the problem.Write struct with data, prev and next pointers.Write a function to insert the node into the doubly linked list.Initialize the doubly linked list with dummy data.Take a node to delete.Write a function to delete the node. Consider the following three cases while deleting the node.If the node is head node, then move the head to next node.If the node is middle node, then link the next node to the previous nodeIf the node is end node, then ...

In this tutorial, we are going to find the deepest left leaf node in the binary tree. Let's see the binary tree.   A       B    C D       E       F                      GLet's see the steps to solve the problem.Write a Node struct with char, left, and right pointers.Initialize the binary tree with dummy data.Write a recursive function to find the deepest left node in the binary function. It takes three argument root node, isLeftNode, and result pointer to store the deepest node.If the ... Read More

In this tutorial, we are going to learn about the fixed partitioning in the operating system.Fixed partitioning is one to manage the memory in operating system. It's an old technique. It divides the memory into equal blocks. The size of each block is predefined and can not be changed.The memory is used for the contiguous processes.ExampleLet's see the sample program that allocates memory based on the process size. Live Demo#include using namespace std; int main() {    int blockNumber = 5, processesNumber = 3;    int blockSize[5] = {4, 4, 4, 4, 4}, processSize[3] = {1, 2, 3};    int flags[5], ...

In this tutorial, we are going to learn how find the first uppercase letter in the given string. Let's see an example.Input −TutorialspointOutput −TLet's see the steps to solve the problem using iterative method.Initialize the string.Iterate over the string.Check whether the current character is uppercase or not using isupper method.If the character is uppercase than return the current character.ExampleLet's see the code. Live Demo#include using namespace std; char firstUpperCaseChar(string str) {    for (int i = 0; i < str.length(); i++)       if (isupper(str[i])) {          return str[i];       }       ...
