The Fermat test is based on a result from number theory known as Fermat’s little theorem.
According to Fermat’s little theorem, if n is a prime number and d is any positive integer less than n, then d raised to the nth power is congruent to d modulo n.
If two numbers have the same remainder when divided by n then they are said to be congruent modulo n. d modulo n is simply the remainder of a number d when divided by n.
For example, 34 is congruent to 16 (modulo 3) as 34 modulo 3 = 1 and…
Have you desired control over the execution context of your multi-threaded environment? Have you encountered challenges emanating from multiple spawned threads not being managed adequately?
One can effectively manage asynchronous computations in a cooperative pattern by adopting coroutines. A coroutine is a method that executes for a certain period, suspends, and permits other coroutines to run. A CoroutineScope
binds all the launched coroutines to a CoroutineContext
. A CoroutineContext is an indexed type-safe heterogeneous map encompassing CoroutineContext.Key
to CoroutineContext.Element
pairs.
The ViewModel
is always bound to the lifecycle of an activity or a fragment. It aids in storing and managing UI-related…
We frequently encounter code that looks like this:
open class ExampleClass {
private var dependencyOne = DependencyOne()
private lateinit var utilDependency: UtilDependency
protected lateinit var dataProvider: DataProvider
protected open fun loadData() {
dataProvider = DataProvider()
utilDependency = UtilDependency(dataProvider)
}
}
In any code, we know one type depends on multiple other types, like ExampleClass
depends on dependencyOne
, utilDependency
, and dataProvider
and it resolves these dependencies using a constructor dependencyOne = DependencyOne()
or maybe even help resolve dependencies for the type it depends on utilDependency = UtilDependency(dataProvider)
.
As developers, we often write tests but we don’t want our tests to be…
Majority of the folks in the programming community start with the plain old “Hello World” when experimenting with a new language.
<?php
echo "Hello World";
?>
Too lazy, use short tags (not recommended):
<?="Hello World"?>
console.log("Hello World");
public class DemoClass{ public static void main(String[] args){
System.out.println("Hello World");
}}
Everything in Java has to be enclosed within a class. A class can be any blueprint that describes the states and behaviours of objects. An object is an instance of a class. An object has state and behaviour.
