using namespace std;
std::string switcheroo(const std::string &s) {
string myString = s;
int i = 0;
int j = s.length();
if(s[i] != 'a' || s[i] != 'b') i++;
if(s[j] != 'a' || s[j] != 'b') j--;
else
{
swap(myString[i],myString[j]);
}
return myString;
}
...ANSWER
Answered 2021-Apr-09 at 14:42Here's a version of the function that passes all tests.
Because the parameter s
is passed in as a reference to const, we can't make changes to it directly. So, we declare a new string, tmp
, and build it letter by letter. The key is looping through s
so that we can examine each letter. If it's 'a'
, be add a 'b'
to tmp
. If it's a 'b'
, we add 'a'
to tmp
. And if it's neither, we just add that letter as-is. By the time the loop finishes, we've looked at every letter in s
and built tmp
with the 'a'
s and 'b'
s swapped. So we return tmp
.
QUESTION
I'm writing some library code that exposes a const pointer to users but during certain operations I need to change where this pointer points (behind the scenes switcheroo tricks). One idea I had to solve this problem without encountering UB or strict-aliasing violations was to use a union with a const member:

QUESTION
I asked a similar question a couple days ago, however I have been working on the project a bit more and got stuck at another problem. The project is that when the mouse is hovering over a button the background switches to another image. I have added a fade-in effect with @keyframes however it only works on they way in and I can't seem to work out the solution. I'm also not sure why the background is flashing at the first hover over the button. Is it just loading time for the image? It happens when I download it and link it locally also. You can see my code and snippet below, thanks for the help!
...ANSWER
Answered 2021-Jan-07 at 17:46Here's a solution, you can add another class on mouseleave
in js, and this time have the keyframes go from that current background image, back to the default one. Take a look:
QUESTION
I'm currently trying to display an admob banner in my app, However there are two pages where I would not like the banner displayed (For now i'm testing with just the settings route), And calling dispose on the banner does not hide it.
What I tried:
- Creating the banner for each widget and calling the dispose method inside the override of the widget's
onDispose
method - Creating an Ad manager class that created the banner and saved a reference to it, and invoking a function from said class that calls dispose on the banner inside the
init
of the page I don't want the banner shown on. - My current solution: an observer class that shows the banner on push, and if the name of the route matches what I'm looking for hides the banner.
So far none of these approaches have been successful :( What am I doing wrong? Am I missing something?

QUESTION
I am currently trying to implement push notifications for my android app with FCM, However when I send a notification it doesn't appear on the phone. I know for sure that the app received the message since it appears in the logcat, but the notification itself doesn't appear and i'm not sure where I went wrong. I got an error from Glide but I tried again without the LargeIcon and the .notify
line outside of the glide line and still nothing appeared. Any help is appreciated :)

QUESTION
first of all I'm just beginning my journey with Python (so you can also ignore all hideous semicolons). It is a simple program as a task at the end of chapter checking what you have learned. Basically it's a "guess the number" but the program has to guess your number (it's a reversed program from book). Maybe it's not the intention of the book and I've yet not learned it but my curiosity took the best of me and I have to ask. How can you remember variables between loops? I think I have to use table and in that way save and check variables between loops, but maybe there is an easier way in Python itself.
In code the program remembers last number it generated but another one is "forgotten" - obviously visable in code. The purpose of this is to minimise attempts of program to guess the number (narrow numbers that are guessed). code to get the idea of program:

QUESTION
The value of the variable 'switcheroo' in the view controller below is always the same when I attempt to access it via a singleton. I am trying to access its value from a custom label class that prints the characters of the label one by one. When the label is set, I try to get the updated value of switcheroo in the Viewcontroller singleton. However it always returns the initial value of switcheroo, not the updated value (which I can trace in the viewcontroller). Am I doing something wrong?
...ANSWER
Answered 2020-Mar-02 at 02:59If you have determined that having a ViewController
singleton is the right decision, the likely answer is that you are not using that shared instance every time, instead accidentally calling the initializer at some point in your project (possibly Xcode is doing it automatically through interfaces).
To search through your entire project, you can use cmd + shift + F and then type TheViewController()
. There should only be one occurrence (the shared instance). Be sure to also check for TheViewController.init()
. That will find any time you do it.
If the issue persists, perhaps try setting the shared instance to self
in the viewDidLoad
method of TheViewController
?
Hope this helps!
