Suppose we have a special binary tree, whose leaf nodes are connected to form a circular doubly linked list. We have to find its height. So the left pointer of the left most leaf will act as previous pointer of circular doubly linked list, and its right pointer will act as next pointer of the linked list.In this case the height finding strategy is similar to the normal binary search tree. We recursively calculate the height of the left and right subtrees of a node and assign height to the node is max of the two children + 1. But ... Read More

Suppose we have three coordinates which are midpoint of sides of the triangle. We have to find the coordinates of the triangle. So if the inputs are like (5, 3), (4, 4), (5, 5), then output will be (4, 2), (4, 6), (6, 4).To solve this, we have to solve for X-coordinates and Y-coordinates separately. For X coordinate of vertices, let them be x1, x2, x3. Then, X-coordinate of middle points will be (x1 + x2)/2, (x2 + x3)/2, (x3 + x1)/2. If we observe the sum of these three expressions is equal to sum of X-coordinates. Now, we have ... Read More

Suppose we have an array A with n elements. And elements are sorted. We have to find the closest value to the given integer. The array may contain duplicate values and negative numbers. So if the array is like [2, 5, 6, 7, 8, 8, 9] and the target number is 4, then closest element is 5.We can solve this by traversing through the given array and keep track of absolute difference of current element with every element. Finally return the element that has minimum absolute difference.Example Live Demo#include #include using namespace std; int getNearest(int x, int y, int target) { ... Read More

To get the total number of elements in a specified dimension of an array, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main() {       string[] products = new string[] { "Andy", "Mark", "Gary", "Andre"};       Console.WriteLine("One or more name begins with 'A'? = {0}",       Array.Exists(products, ele => ele.StartsWith("A")));       Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);       Console.WriteLine("Is the array read only? = " + products.IsReadOnly);       Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized); ...

To set the capacity to the actual number of elements in a SortedList object, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args) {       SortedList sortedList = new SortedList();       sortedList.Add("A", "1");       sortedList.Add("B", "2");       sortedList.Add("C", "3");       sortedList.Add("D", "4");       sortedList.Add("E", "5");       sortedList.Add("F", "6");       sortedList.Add("G", "7");       sortedList.Add("H", "8");       sortedList.Add("I", "9");       sortedList.Add("J", "10");       Console.WriteLine("SortedList elements...");     ...

To set the capacity to the actual number of elements in the ArrayList, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main(String[] args) {       ArrayList list1 = new ArrayList();       list1.Add("A");       list1.Add("B");       list1.Add("C");       list1.Add("D");       list1.Add("E");       list1.Add("F");       list1.Add("G");       list1.Add("H");       list1.Add("I");       Console.WriteLine("Elements in ArrayList1...");       foreach (string res in list1) {          Console.WriteLine(res);     ...

To search for an element matching the conditions and return the zero-based index of the last occurrence within the entire List, the code is as follows −Example Live Demousing System; using System.Collections.Generic; public class Demo {    private static bool demo(int i) {       return ((i % 10) == 0);    }    public static void Main(String[] args) {       List list = new List();       list.Add(200);       list.Add(215);       list.Add(310);       list.Add(500);       list.Add(600);       Console.WriteLine("List elements...");       foreach (int i in ...

To search the index of specified object in Collection, the code is as follows −Example Live Demousing System; using System.Collections.Specialized; public class Demo {    public static void Main() {       StringCollection strCol = new StringCollection();       strCol.Add("Accessories");       strCol.Add("Books");       strCol.Add("Electronics");       strCol.Add("Books");       Console.WriteLine("StringCollection elements...");       foreach (string res in strCol) {          Console.WriteLine(res);       }       strCol.Insert(2, "Headphone");       Console.WriteLine("StringCollection elements...UPDATED");       foreach (string res in strCol) {          Console.WriteLine(res); ...

To get the number of elements contained in the BitArray, the code is as follows −Example Live Demousing System; using System.Collections; public class Demo {    public static void Main() {       BitArray arr1 = new BitArray(5);       BitArray arr2 = new BitArray(5);       arr1[0] = false;       arr1[1] = false;       arr2[0] = false;       arr2[1] = true;       Console.WriteLine("BitArray1 elements...");       foreach (bool res in arr1) {          Console.WriteLine(res);       }       Console.WriteLine("BitArray2 elements...");     ...

To check whether a thread is alive or not, the code is as follows −Example Live Demousing System; using System.Threading; public class Demo {    public static void Main() {       Thread thread = new Thread(new ThreadStart(demo1));       thread = Thread.CurrentThread;       Console.WriteLine("Is the thread alive? = "+thread.IsAlive);       ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));       Console.WriteLine("Current state of Thread = "+thread.ThreadState);       Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);       thread.IsBackground = true;       Console.WriteLine("Is the Thread a background thread? = "+thread.IsBackground);    }    public static void demo1() {     ...
