Firstly, set the string to be checked.string s = "timetime";Now set two counters for two halves of the string.int []one = new int[MAX_CHAR]; int []two = new int[MAX_CHAR];Check for both the halves of the string.for (int i = 0, j = l - 1; i < j; i++, j--) { one[str[i] - 'a']++; two[str[j] - 'a']++; }The following is the complete code to check whether both the halves of the string have same set of characters or not in C#.Example Live Demousing System; class Demo { static int MAX_CHAR = 26; static bool findSameCharacters(string str) { ...

To set the starting position of a background image in JavaScript, use the backgroundposition property. It allows you to set the position of the image.ExampleYou can try to run the following code to learn how to set all the position of a background image with JavaScript −Live Demo body { background-repeat: no-repeat; } Click to Set background image function display() { document.body.style.backgroundImage = "url('https://www.tutorialspoint.com/html5/images/html5-mini-logo.jpg')"; document.body.style.backgroundPosition="top right"; }
Firstly, set the two numbers.int one = 250; int two = 200;Now pass those numbers to the following function.public int RemainderFunc(int val1, int val2) { if (val2 == 0) throw new Exception("Second number cannot be zero! Cannot divide by zero!"); if (val1 < val2) throw new Exception("Number cannot be less than the divisor!"); else return (val1 % val2); }Above we have checked for two conditions i.e.If the second number is zero, an exception occurs.If the first number is less than the second number, an exception occurs.To return remainder of two numbers, the following is ...

Use the Number() method in JavaScript to convert to Number. You can try to run the following code to learn how to convert ["demo"] to Number in JavaScript −ExampleLive Demo Convert ["demo"] to Number var myVal = ["demo"]; document.write("Number: " + Number(myVal));
The BitArray class is used when you need to store the bits but do not know the number of bits in advance.Using the IsReadOnly class, you can get a value indicating whether the BitArray is read-only or not. ReadOnly will not allow you to add new elements to the BitArray.The following is our example stating how to use the IsReadOnly property of BitArray class in C#.Example Live Demousing System; using System.Collections; namespace Demo { class Program { static void Main(string[] args) { BitArray ba1 = new BitArray(5); BitArray ba2 ...

Gets an ICollection containing the keys in the Hashtable. It displays all the keys in the collection. In the below code, to get all the keys we have used a loop to loop through the collection.foreach (int k in h.Keys) { Console.WriteLine(k); }The above displays all the keys as shown in the following code −Example Live Demousing System; using System.Collections; class Program { static void Main() { Hashtable h = new Hashtable(); h.Add(1, "India"); h.Add(2, "US"); h.Add(3, "UK"); h.Add(4, "Australia"); h.Add(5, "Netherland"); foreach (int k in h.Keys) { Console.WriteLine(k); } } }Output5 4 3 2 1
Firstly, set three arrays.int[, ] arr1 = new int[20, 20]; int[, ] arr2 = new int[20, 20]; int[, ] arr3 = new int[20, 20];Now users will enter values in both the matrices. We have to set the row and size columns as n=3, since we want a square matrix of 3x3 size i.e 9 elements.Add both the matrices and print the third array that has the sum.for(i=0;i
A nested class is a class declared in another enclosing class. It is a member of its enclosing class and the members of an enclosing class have no access to members of a nested class.Let us see an example code snippet of nested classes in C#.Exampleclass One { public int num1; public class Two { public int num2; } } class Demo { static void Main() { One a = new One(); a.num1++; One.Two ab = new One.Two(); ab.num2++; } ...

For secure random numbers, use the RNGCryptoServiceProvider Class. It implements a cryptographic Random Number Generator.Using the same class, we have found some random values using the following −using (RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider()) { byte[] val = new byte[6]; crypto.GetBytes(val); randomvalue = BitConverter.ToInt32(val, 1); }To generate random secure numbers, you can try to run the following code.Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text.RegularExpressions; using System.Security.Cryptography; public class Demo { public static void Main(string[] args) { for (int i = 0; i
A class can be derived from more than one class or interface, which means that it can inherit data and functions from multiple base classes or interfaces.The derived class inherits the base class member variables and member methods. Therefore, the super class object should be created before the subclass is created. You can give instructions for superclass initialization in the member initialization list.Here you can see object is created for the inherited class.Example Live Demousing System; namespace Demo { class Rectangle { protected double length; protected double width; public Rectangle(double l, ...
