To generate characters, you can utilize the thread-local random number generator function, random.
fn main() {
let tuple = rand::random::<(f64, char)>();
println!("{:?}", tuple)
}
For occasional or singular requests, such as the one above, this is a reasonable efficien...
To mock a protected member you must first include the following at the top of your test fixture:
using Moq.Protected;
You then call Protected() on your mock, after which you can use the generic Setup<> with the return type of your method.
var mock = new Mock<MyClass>();
mock.Protec...

These are the default special characters

Generate a random letter between a and z by using the Next() overload for a given range of numbers, then converting the resulting int to a char
Random rnd = new Random();
char randomChar = (char)rnd.Next('a','z');
//'a' and 'z' are interpreted as ints for parameters for Next()
Based on a question. The following snippets Does not cache the expected emission and prevents further calls. Instead it re-subscribes to the realSource for every subscription.

var realSource = Rx.Observable.create(observer => {

Assume we need to add an NSString object to SomeClass (we cant subclass).
In this example we not only create an associated object but also wrap it in a computed property in a category for extra neatness
#import <objc/runtime.h>
@interface SomeClass (MyCategory)
// This is the property wr...
This example echoes the special character ! into a file. This would only work when DelayedExpansion is disabled. When delayed expansion in enabled, you will need to use three carets and an exclamation mark like this:
@echo off
setlocal enabledelayedexpansion
echo ^^^!>file
echo ^>>&...
BFS can be used to find the connected components of an undirected graph. We can also find if the given graph is connected or not. Our subsequent discussion assumes we are dealing with undirected graphs.The definition of a connected graph is:
A graph is connected if there is a path between every p...

LINQ queries do not execute immediately. When you are building the query you are simply storing the query for future execution. Only when you actually request to iterate the query is the query executed (e.g. in a for loop, when calling ToList, Count, Max, Average, First, etc.)
This is considered de...
Sometimes, we have to take input from users which should contain only alpha numeric characters.
For example, lets say a Username system which allow only letters and numbers,
Then this can be done with the following Regular Expression
^[a-zA-Z0-9]+$
^ is restrict the start
[a-zA-Z0-9]+ is th...
Since both R and regex share the escape character ,"\", building correct patterns for grep, sub, gsub or any other function that accepts a pattern argument will often need pairing of backslashes. If you build a three item character vector in which one items has a linefeed, another a tab ch...
The protected scope allows the value to be accessed from any subclasses of the current class.
class FooClass {
protected val x = "foo"
}
class BarClass extends FooClass {
val y = x // It is a subclass instance, will compile
}
class ClassB {
val f = new FooClass
f.x // <...
The package protected scope allows the value to be accessed only from any subclass in a specific package.
package com.example {
class FooClass {
protected[example] val x = "foo"
}
class ClassB extends FooClass {
val y = x // It's in the protected scope, will compile
