Find winner of an election where votes are represented as candidate names in C++
In this tutorial, we are going to write a program that finds the election winner. We will have an array of votes that each candidate got in the election. Let's see an example.Input {"A", "B", "C", "B", "A", "C", "D", "D", "A", "B", "D", "B", "A", "C", "D"}Output AHere, A and B got the same number of votes. In that case, we have to select the winner based on the alphabetical order of their names.Let's see the steps to solve the problem.Initialize an array of string with dummy data.Initialize a map with string as key and int as value.Iterate over the votes ...
Read MoreFind zeroes to be flipped so that number of consecutive 1's is maximized in C++
In this tutorial, we are going to find the zeroes count that need to be flipped to get maximum number of consecutive 1's in the array.We are going to use the sliding window approach to solve the problem. Let's see the steps to solve the problem.Initialize the array and max zeroes to be flipped.Initialize window starting, ending indexes along with the length.Store the max sub array of consecutive 1's length and starting index.Iterate over the array until ending indexes crosses the array length.If the zeroes count is less than the max zeroes count then increment the ending index and zeroes ...
Read MoreDeepest left leaf node in a binary tree in C++
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 MoreDelete a Doubly Linked List node at a given position in C++
In this tutorial, we are going to learn how to delete a node in doubly linked list with the given position.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.Initialize the position to delete the node.Iterate over the linked list and find the node with the given position to 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 ...
