Here we will see how to get the sorted sequence using B-Tree. The B-tree is n-ary tree. To get the sorted sequences, we can create a B-tree, then add the numbers into it. Here the B-tree can hold maximum 5 nodes. If number of nodes increases, split the node and form new level. As the nodes are holding few number of elements like 5 (at most), we are using Bubble sorting techniques to sort them. as the number of elements is very low, then it will not affect too much on its performance.After traversing the tree, we will get all ...

To set the alignment of the label content along the Y axis, use the setVerticalAlignment() method. Let us first set a label component. We have set the label background color as well so that we can check the alignment of the label’s content properly −JLabel label = new JLabel("Product Name "); label.setPreferredSize(new Dimension(190, 100)); label.setOpaque(true); label.setBackground(Color.ORANGE);Now, we will align the label content along the Y axis −label.setVerticalAlignment(JLabel.CENTER);The following is an example to set the alignment of the JLabel content along the Y axis −Examplepackage my; import java.awt.Color; import java.awt.Dimension; import java.awt.FlowLayout; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JTextArea; import javax.swing.WindowConstants; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Our Frame ...

You can use $in operator. Let us first create a collection with documents −> db.tagCountDemo.insertOne({"ListOfNames":["John", "Sam", "Carol"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b387924bb85b3f48944") } > db.tagCountDemo.insertOne({"ListOfNames":["Bob", "David", "John"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b4b7924bb85b3f48945") } > db.tagCountDemo.insertOne({"ListOfNames":["Mike", "Robert", "Chris"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b5d7924bb85b3f48946") } > db.tagCountDemo.insertOne({"ListOfNames":["James", "Carol", "Jace"]}); { "acknowledged" : true, "insertedId" : ObjectId("5cd64b717924bb85b3f48947") }Following is the query to display all documents from a collection with the help of find() method −> db.tagCountDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd64b387924bb85b3f48944"), "ListOfNames" : ...

In this section we will see the isnormal() function in C++. This function is present in the cmath library. This function is used to check whether a number is normal or not. The numbers that are considered as non-normal are zeros, infinity or NAN.This function takes float, double or long double values as argument. Returns 1 if the number is normal, otherwise returns 0.Example Live Demo#include #include using namespace std; int main() { cout
Enumeration (enum) in Java is a datatype which stores a set of constant values (Strings in general). You can use enumerations to store fixed values such as days in a week, months in a year etc.enum Days { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY }Custom values to the constantsInstead of declaring just string constants in an enum, you can also have values to these constants as −enum Vehicles { ACTIVA125(80000), ACTIVA5G(70000), ACCESS125(75000), VESPA(90000), TVSJUPITER(75000); }Whenever, you need to assign custom values to the constants of an enum −To hold the value of each ...

Here, the task is to print those number in an array having 1, 2 and 3 as digits in their numbers and if their is no such number than the output must be -1Input : arr[] = {320, 123, 124, 125, 14532, 126, 340, 123400, 100032, 13, 32, 3123, 1100} Output : 123 3123 14532 100032 123400 Since the array have values with digits 1, 2 and 3 it wouldn’t return -1 and print 5 values that Contain 1, 2 and 3 in their respective numbers.AlgorithmSTART Step 1 -> Declare array with elements of int type as arr Step ...

You can use every() in MongoDB for this. Let us create a collection with documents −> db.arrayConditionDemo.insertOne({"Name":"John", "Marks":[40, 43, 45]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd06de8cc557214c0e1a") } > db.arrayConditionDemo.insertOne({"Name":"Mike", "Marks":[45]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd17de8cc557214c0e1b") } > db.arrayConditionDemo.insertOne({"Name":"Chris", "Marks":[43, 45, 59, 69, 78, 89]}); { "acknowledged" : true, "insertedId" : ObjectId("5cbdbd3cde8cc557214c0e1c") }Display all documents from a collection with the help of find() method. The query is as follows −> db.arrayConditionDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cbdbd06de8cc557214c0e1a"), "Name" : "John", "Marks" : [ ... Read More
In a Directed Acyclic Graph, we can sort vertices in linear order using topological sort.Topological sort is only work on Directed Acyclic Graph. In a Directed Acyclic Graph (DAG), there can be more than one topological sort.In the following C++ program, we shall perform topological sort to check existence of a cycle in a graph.AlgorithmsFor function Topo_SortBegin Define function Topo_Sort() Declare x to the integer datatype, vstd[] of the Boolean array and Stack as a stack. Pass them as parameter. Initialize vstd[x] = true to mark the current node ... Read More
