Suppose we have a number n denotes n people and there are two identical voting machines. We also have an array called time of size n such that time[i] represents total time spent by i-th person to vote on any machine. At one time instant, only one person can be there on each of the two machines. We also have another value x, representing the maximum allowable time for which machines are operational, we have to check whether all persons can place their vote or not.So, if the input is like n = 3, x = 7, time = [3, ...

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.Delete alternate node by maintaining the previous 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 node.If the node is middle node, then link the next node to ... Read More
