            How to make a stack view with subviews that has different alignments?
            Asked 2021-Apr-19 at 00:55

            My goal

            I am making a UI that has an image at the top, and four buttons below it, arranged vertically. The height of the image depends on its width, but it shouldn't be too tall that there isn't enough space for the buttons. After the image is positioned, the buttons can fill up the rest of the space. Horizontally, The image should try to take up as much of the width of the screen as possible, but the buttons should have a constant width of 300 and be centered horizontally. I understand that this is a bad idea for localisation, but I don't plan on localising this app.

            A picture is worth 1000 words:

            I have only used the stack overflow logo to replace the actual image that I will be using. I am not making a Stack Overflow-related app.

            Also, the image view should be on the left of the buttons when the vertical size class is compact (the buttons are still vertically arranged).

            I think I basically wanted a stack view whose subviews are aligned differently - the image view is aligned with "Fill", and the buttons are aligned with "Center". However, I don't know how to do that, so I tried to use nested stack views to work around this.

            How to reproduce:

            The outer stack view top/bottom/leading/trailing all are pinned to the VC's view, alignment set to "Fill", distribution set to "Fill Proportionally". I chose "Fill Proportionally" because I found that works the best if I use a large enough image. I added a variation on the outer stack view's axis, so that it is set to horizontal when vertical size class is compact.

            The outer stack view has 2 arranged subviews - the image view and the inner stack view, whose distribution is set to "Fill", alignment is set to "Center".

            The inner stack view then has those buttons. Each button has a constant width constraint.

            I thought that should do the job. When I run the app, I see some "unable to satisfy constraints" warnings:

            ...

            Answered 2021-Apr-18 at 15:29

            OK - based on the image you posted, I'm going to use a 2:1 aspect ratio for your "Logo Image"...

            Start with a "basic" layout:

            Here's the constraints:

            the Outer StackView properties:

            and the Buttons StackView properties:

            At this point, we should be "good to go" with "portrait" layout.

            Let's add some trait variations...

            To get this layout:

            We'll add `Width: Any / Height: Compact" for the Axis and Alignment of the OuterStack:

            and we'll add `Width: Any / Height: Compact" for the Alignment of the ButtonsStack:

            If we run that (iPhone 12 sim), we get this:

            We're close, but... we get a whole mess of auto-layout warning / error messages in the debug console.

            That's because (from my experience) auto-layout needs to make multiple "passes" to fully evaluate the layout, particularly when using Aspect-Ratio constraints mixed with Stack Views.

            To get rid of that, we'll give the Image View's Aspect-Ratio constraint a less-than-required Priority:

            This, effectively, allows auto-layout to break constraints during its multiple layout passes.

            Instead of generating a list between ord(i[0]) and ord(i[1]), and finding its length, there's a better solution, just finding the difference between ord(i[0]) and ord(i[1]).

            This doesn't immediately solve the issue for reversed alphabets, since a reversed alphabet would generate a negative number, but you can solve this with the builtin abs() function which takes the absolute value of a number:

            You need to return cleanup function from effect, so when fast refresh will rerun it, there will be no duplicates. It works properly sometimes because sometimes fast refresh sometimes don't try to preserve state and renders everything as new. This depends on changes you made, so when you change one file it will render clean, but on another files it will try to preserve state and only rerun effects (this is where second board added).

            Also, it is better not to interact with DOM directly and use ref instead. This is better way to work with DOM in react, since it's react main purpose to update DOM.

            You can use the DOM to change CSS styles. All you have to do is add image.style.padding = "enter padding in px";. Put this code before you append the image. You can use the DOM to change the css styles of any property. Just add element.style.csspropertyhere = "value";

            QUESTION

            How is the ArrayList add(Type value) method O(1) amortized time complexity?
            Asked 2020-Nov-10 at 16:32

            Most implementations of the ArrayList use an array internally and when the size is already exhausted upon adding an element to the list, it resizes or "grows" by essentially doing the following:

            • caching a new array with a new batch of freshly allocated memory.
            • copying all the elements of the internal array into the new array.
            • setting the internal array to the new array.
            • setting index N - 1 of the internal array to the element object, where N is the new size of the array.

            The explanation provided is that growing the list is a rare necessity for your average add operation so the time complexity of the average add is O(1), hence amortized constant time.

            I am confused as to how this makes sense. Say the list grows by Q. Simple arithmetic series will show you that if I were to add x elements to an ArrayList, the total number of element copies done internally is x^2 + Qx / 2Q, if x were several times larger than Q.

            Sure, for the first few values that are added the time may very well be constant, but for a large enough number of elements added we're seeing the average time complexity for each add operation to be linear or O(n). Hence, adding a large number of elements to the list takes exponential time. I don't understand how even the amortized time complexity of a single add operation is constant. Is there something I'm missing?

            EDIT: I did not realize that the list growth is in fact geometric and this optimizes the amortized time complexity.

            Conclusion:

            Linear Growth of Dynamic List

            Without loss of generality, suppose the initial capacity of the list is 1. We further assume that the capacity is doubled each time the capacity is exceeded by an insertion. Now consider inserting 2^k + 1 elements (which is the general worst case, since the last operation triggers the dynamic growing).

            There are k insertions that trigger dynamic growing, and their accumulative cost is
