In this problem, we have to create a function that will generate three numbers based on the given probability.For this, we will use the built-in random number generator function which is rand(a, b) which generates random numbers within the range [a, b] with equal probability.Our task is to return only three numbers A, B, C which have the probability of occurrence as P(A), P(B), P(C) respectively and according to definition of probability P(A) + P(B) + P(C) = 1.To create our function using rand(a, b). we will use its feature that the probability of occurrence of any number from a ...

Here, we will create a function that will delete all elements of a linked list one by one.In c/c++, there is no specific function to perform this task but in java, the automatic garbage collection is done to ease deleting linked list.Now, let’s see the implementation of this program, Example Live Demo#include using namespace std; class Node{ public: int data; Node* next; }; void deleteLinkedList(Node** head_ref){ Node* current = *head_ref; Node* next; while (current != NULL){ coutnext = (*head_ref); (*head_ref) = new_node; } int main(){ Node* head = NULL; ...

LongToIntFunction is a functional interface from java.util.function package introduced in Java 8. This functional interface accepts a long-valued parameter as input and produces an int-valued result. LongToIntFunction interface can be used as an assignment target for a lambda expression or method reference. This interface contains only one abstract method: applyAsInt() and doesn't contain any default and abstract methods.Syntax@FunctionalInterface interface LongToIntFunction { int applyAsInt(long value); }Example of Lambda Expressionimport java.util.function.LongToIntFunction; public class LongToIntLambdaTest { public static void main(String args[]) { LongToIntFunction getInt = longVal -> { // lambda expression int intVal = (int)longVal; ...

LongToDoubleFunction is a built-in functional interface and part of java.util.function package. This functional interface accepts a long-valued parameter as input and produces a double-valued result. LongToDoubleFunction can be used as an assignment target for a lambda expression or method reference. It contains only one abstract method: applyAsDouble().Syntax@FunctionalInterface interface LongToDoubleFunction { double applyAsDouble(long value); }Example of Lambda Exampleimport java.util.function.LongToDoubleFunction; public class LongToDoubleLambdaTest { public static void main(String args[]) { LongToDoubleFunction getDouble = longVal -> { // lambda expression double doubleVal = longVal; return doubleVal; }; long input = ...

In order to disable future dates, you need to use maxDate and set the current date. Following is the JavaScript code −Example Live Demo Document The selected date is as follows: $(document).ready(function () { var currentDate = new Date(); $('.disableFuturedate').datepicker({ format: 'dd/mm/yyyy', autoclose:true, endDate: "currentDate", maxDate: currentDate }).on('changeDate', function (ev) { $(this).datepicker('hide'); }); $('.disableFuturedate').keyup(function () { ...

For this, you need to use keyDown as well as preventDefault(). Following is the JavaScript code −Example Live Demo Document const pressEnter = (event) => { if (event.key === "Enter") { event.preventDefault(); } }; document.getElementById("disableDefaultTime").addEventListener("keydown", pressEnter); To run the above program , just save the file name anyName.html(index.html) and right click on the file and select the option open with live server in VSCode editor.OutputFollowing is the output. When you press Enter key nothing will be displayed.You need to use keyDown to get time as in the below screenshot −
For this, you need to use attr(). The attr() method can be used to either fetch the value of an attribute from the first element in the matched set or set attribute values onto all matched elements.Following is the JavaScript code −Example Live Demo Document $('#myURL').attr('value', 'http://www.facebook.com'); To run the above program, just save the file name anyName.html(index.html) and right click on the file and select the option open with live server in VSCode Editor.OutputLook at the above sample output the URL has been changed ...
