Don't optimize as you go:
Write your program without regard to possible optimizations, concentrating instead on making sure that the code is clean, correct, and understandable. If it's too...
Generator comprehensions follow a similar format to array comprehensions, but use parentheses () instead of square brackets [].
(expression for element = iterable)
Such an expression returns a Generator object.

Goto accepts the use of variable value to act as the label to goto.
Example:
@echo off
echo a = 1
echo b = 2
set /p "foo=Enter option:"
goto %foo%

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...
Suppose we'd like to invoke the JavaScript function JSON.stringify which receives an object, encodes it into a JSON string and returns it.
All we'd have to do is write the function signature, mark it as external and annotate it with the @JS annotation:
@JS("JSON.stringify")
external St...
