int i, space, rows, k=0, count = 0, count1 = 0; row=5; for(i=1; i<=rows; ++i) { for(space=1; space <= rows-i; ++space) { printf(" "); ++count; } while(k != 2*i-1) { if (count <= rows-1) { printf("...

Some digital image processing algorithm such as edge detection, information carried by the image intensity (i.e. grayscale value) is sufficient. Using color information (R, G, B channel) may provides slightly better result, but the algorithm complexity will be increased. Thus, in this case, we need ...

The following rules define a simple strategy for creating immutable objects. Don't provide "setter" methods - methods that modify fields or objects referred to by fields. Make all fields final and private. Don't allow subclasses to override methods. The simplest way to do this is to d...

public final class Color { final private int red; final private int green; final private int blue; private void check(int red, int green, int blue) { if (red < 0 || red > 255 || green < 0 || green > 255 || blue < 0 || blue > 255) { throw ...

In this case class Point is mutable and some user can modify state of object of this class. class Point { private int x, y; public Point(int x, int y) { this.x = x; this.y = y; } public int getX() { return x; } public void setX(int ...

Bubble sorting with rules and replacements: list = {1, 4, 2, 3, 6, 7, 8, 0, 1, 2, 5, 4} list //. {fsts___, x_, y_, lsts___} :> {fsts, y, x, lsts} /; y < x (* Out[1] := {1, 4, 2, 3, 6, 7, 8, 0, 1, 2, 5, 4} Out[1] := {0, 1, 1, 2, 2, 3, 4, 4, 5, 6, 7, 8} *)

Since BackAndroid is deprecated. Use BackHandler instead of BackAndroid. import { BackHandler } from 'react-native'; {...} ComponentWillMount(){ BackHandler.addEventListener('hardwareBackPress',()=>{ if (!this.onMainScreen()) { this.goBack(); return true; ...

<?php include "vendor/autoload.php"; $app = new \Slim\App(); $app->get('/hello', function () { echo "Hello, world"; }); $app->run();

Anonymous functions technique uses the fact that CALL command uses internally GOTO when subroutine is called and abusing help message printing with variable double expansion: @echo off setlocal set "anonymous=/?" call :%%anonymous%% a b c 3>&1 >nul if "%0" == ...

Lets have the following file called library.cmd : @echo off echo -/-/- Batch Functions Library -/-/- :function1 echo argument1 - %1 goto :eof To execute only the :function1 without the code of the rest of the file you should put a label :function1 in the caller bat and use it lik...

The easiest way to connect via curl to a different server is to alter the hosts file on your machine. On Linux and Unix systems, the hosts file is located in /etc/hosts, while on Windows systems it will be located in c:\windows\system32\drivers\etc\hosts. Once you open the file with a text editor ...

First is first, ensure that USE_TZ = True in your settings.py file. Also set a default time zone value to TIME_ZONE such as TIME_ZONE='UTC'. View a complete list of timezones here. If USE_TZ is False, TIME_ZONE will be the time zone that Django will use to store all datetimes. When USE_TZ is enable...

I wrote a simple C code foo.c int main() { int i = 0; int j = 0; for (i = 0; i < 5; i++) { j = i + 1; } return 0; } When compiled with -O0 i.e. by disabling all compiler optimizations $ gcc -o foo.S foo.c -O0 -S I got this: .file "foo.c&...

var foo : Int by Delegates.observable("1") { property, oldValue, newValue -> println("${property.name} was changed from $oldValue to $newValue") } foo = 2 The example prints foo was changed from 1 to 2

class MyDelegate { operator fun getValue(owner: Any?, property: KProperty<*>): String { return "Delegated value" } } val foo : String by MyDelegate() println(foo) The example prints Delegated value

interface Foo { fun example() } class Bar { fun example() { println("Hello, world!") } } class Baz(b : Bar) : Foo by b Baz(Bar()).example() The example prints Hello, world!
