Why use Abstract Base Classes in Python?
...sinstance(c, MyABC): # will be true
c.abc_method() # raises AttributeError
Unfortunately this one of those "just don't do that" traps (of which Python has relatively few!): avoid defining ABCs with both a __subclasshook__ and non-abstract methods. Moreover, you should make your definition of...
Injecting $scope into an angular service function()
.... show a notification.
}, function (err) {
// Handle the error.
});
};
}
]);
One thing you should be careful about when using this approach is to never re-assign the service's array, because then any other components (e.g. scopes) will be still referencing th...

Finding three elements in an array whose sum is closest to a given number
... a better solution because it's easier to read and therefore less prone to errors. The only problem is, we need to add a few lines of code to avoid multiple selection of one element.
Another O(n^2) solution (by using a hashset).

for i 1..n

How to declare a global variable in a .js file
...oes it alert "Hello" or "Howdy" ?
However, this is much cleaner and less error prone (you don't really need to remember all the variable scoping rules):
function foo() {
window.greeting = "Hello";
}
function bar(greeting) {
alert(greeting);
}
foo();
bar("Howdy"); // alerts "Howdy"...
