An is even function that is technically correct, but a really bad approach.

Takes an unsorted array of integers, sorts by sleeping for the int value of each item in the array and then writing that into the resulting sorted array. Big-O analysis is... difficult.

Was trying to find a very specific text box and as an AngularJS noob, this was the only way I could find it at first. I eventually figured out how to not do this before it ever got committed to production though. :)

    Result := true;

  end;

Result := ((p_Id = 'A') or (p_Id = 'B'));

That would have been enough. But this also features Exit and an asymmetrical if.

How to create immutable fields in c#

    UIButton * btn = [UIButton new];
    [btn addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];

    [btn setTitle:[NSString stringWithFormat:@"  %@  ", btnTxt] forState:UIControlStateNormal];
    [btn sizeToFit];
    [btn setTitle:btnTxt forState:UIControlStateNormal];

Why keep playing with label padding or insets when you can add spaces?

                    if(date.getSeconds() <= 59) {
                        //Display popup before 2017-11-27
                    }

def copy( variable ):
    return variable
