As you can see in the above sample piece of code we are trying to parse the string to Int. In the first line we have the main function which is responsible to start the execution of the Haskell program, In the next step we are defining one variable called ‘demo’ which will hold th...
Haskell tuple is the structure by which we can manage to store or group the values inside it. The tuple in Haskell is a fixed sized structure which can hold any type of data type inside it. We may have some requirements where we want to store different type of values inside the object,...

1. Base widgets:They help the other derived widgets to function through it. They are also known as ancestors and they generally do not function directly. Some of its examples are wxControl, wxWindows, etc. 2. Top-level widgets:They do not depend on other widgets, such as wxFrame, wxScro...
In a call to reduce(<f>, <iterable>), the function <f> must be a function that takes exactly two arguments. reduce() will then progressively combine the elements in <iterable> using <f>. To start, reduce() invokes <f> on the first two elements of <iterable>. That result is then...
The above lambda function is equivalent to writing this:Python def add_one(x): return x + 1 These functions all take a single argument. You may have noticed that, in the definition of the lambdas, the arguments don’t have parentheses around them. Multi-argument functions (functions that...
neither an object-oriented nor a functional programming language. It doesn’t feature classes and doesn’t directly support object-oriented patterns. It can operate with functions as first-class values, but this ability is limited compared to full-blown functional languages (such as Haskell or ...

Step 2: bundle the binary with a Lambda function The statically linked Pandoc binary is roughly 50 MB. Lambda has alimit of 50 MB for the total package size, so we’ll send up a compressed version. Gzip brings the binary size down to roughly 11 MB, which is a lot better. We’ll ...
OTOH The issue with a pure pull approach is when we deal with future values. I mean, when we call a function that may take some noticeable time before it can delivers its result (a common case is when you make a call to a remote server) // server data may take a long time to re...
