LINQ provides a built-in function for checking the equality of two IEnumerables, and that function can be used on arrays.
The SequenceEqual function will return true if the arrays have the same length and the values in corresponding indices are equal, and false otherwise.
int[] arr1 = { 3, 5, 7 };...

In Solution Explorer go to your project, right click on References then Add reference…
Search for Compression and select System.IO.Compression.FileSystem then press OK.
Add Imports System.IO.Compression to the top of your code file (before any class or module, with the other Imports statements)....
The zip function accepts 2 parameters of type SequenceType and returns a Zip2Sequence where each element contains a value from the first sequence and one from the second sequence.
Example
let nums = [1, 2, 3]
let animals = ["Dog", "Cat", "Tiger"]
let numsAndAnimals ...
Compiler definitions run platform specific code. Using them you can make small differences between various platforms.
Trigger Game Center achievements on apple devices and google play achievements on Android devices.
Change the icons in menus (windows logo in windows, Linux penguin in Linux).

Notepad++ provides 2 types of features for auto-completion and suggestions:
Auto-completion that reads the open file and provide suggestion of words and/or functions within the file
Suggestion with the arguments of functions (specific to the language)
To enable it, you need to change a settin...
.default-settings() {
padding: 4px;
margin: 4px;
font-size: 16px;
border: 1px solid gray;
}
#demo {
.default-settings;
}
The above example when compiled would only produce the following output. The .default-settings() mixin definition would not be output in the compiled CSS fi...
Intent:
Separate the construction of a complex object from its representation so that the same construction process can create different representations
Builder pattern is useful when you have few mandatory attributes and many optional attributes to construct a object. To create an object with dif...
Clone the SFML Repository from Github.
Enter following comands in a cmd window:
git clone https://github.com/SFML/SFML.git SFML
If you already downloaded SFML before you can just use the existing one.
Create some folders for the build-files
cd SFML
mkdir build && cd build
mkdir ar...
You can disable compiler warnings using #pragma warning disable and restore them using #pragma warning restore:
#pragma warning disable CS0168
// Will not generate the "unused variable" compiler warning since it was disabled
var x = 5;
#pragma warning restore CS0168
// Will gene...
Principal Component Analysis finds sequences of linear combinations of the features. The first linear combination maximizes the variance of the features (subject to a unit constraint). Each of the following linear combinations maximizes the variance of the features in the subspace orthogonal to that...
Arrow is, vaguely speaking, the class of morphisms that compose like functions, with both serial composition and “parallel composition”. While it is most interesting as a generalisation of functions, the Arrow (->) instance itself is already quite useful. For instance, the following function:
sp...
Various websites provide online access to C++ compilers. Online compiler's feature set vary significantly from site to site, but usually they allow to do the following:
Paste your code into a web form in the browser.
Select some compiler options and compile the code.
Collect compiler and/or pro...
The "child" components of a component are available on a special prop, props.children. This prop is very useful for "Compositing" components together, and can make JSX markup more intuitive or reflective of the intended final structure of the DOM:
var SomeComponent = function ...
You can use Modules to build more complex classes through composition. The include ModuleName directive incorporates a module's methods into a class.
module Foo
def foo_method
puts 'foo_method called!'
end
end
module Bar
def bar_method
puts 'bar_method called!'
end
end
...
With Parallel List Comprehensions language extension,
[(x,y) | x <- xs | y <- ys]
is equivalent to
zip xs ys
Example:
[(x,y) | x <- [1,2,3] | y <- [10,20]]
-- [(1,10),(2,20)]
A few pre-requisites in the build.gradle for vectors to work all the way down to API 7 for VectorDrawables and API 13 for AnimatedVectorDrawables (with some caveats currently):
//Build Tools has to be 24+
buildToolsVersion '24.0.0'
defaultConfig {
vectorDrawables.useSupportLibrary = true

Use tf.nn.sparse_softmax_cross_entropy_with_logits, but beware that it can't accept the output of tf.nn.softmax. Instead, calculate the unscaled activations, and then the cost:
logits = tf.matmul(state_below, U) + b
cost = tf.nn.sparse_softmax_cross_entropy_with_logits(logits, labels)
In this c...
