QUESTION
I have trouble understanding the first line of code inside this implementation of the bsearch function in C. I understand the search algorithm itself and I have played around with this function to get a good grasp of it but I still do not get what
...ANSWER
Answered 2021-Jun-15 at 21:44Within the function you need to find each element in the passed array. However the type of the array is unknown. You only know the size of each element of the array and the starting address of the array that is passed through the parameter base0. of the type const void *
..
To access an element of the array you need to use the pointer arithmetic. But the type void is incomplete type. Its size is unknown/ So you may not use the pointer of the type (const) void *` in expressions with the pointer arithmetic.
Thus this declaration

Consider this code:
...ANSWER
Answered 2021-Mar-12 at 12:54Try not not imagine as "array traversing", but follow what does the for loop actually do: You declare a variable i
and increment it after every iteration and using it to access the arrays. For the outer array, you say "give me first, second, third, ... element" (a[i]
). That's equivalent to for each in lists - you go over all elements of the outer array. But on the result (inner array), you access i
th element again (a[i][i]
) - which means that you're not iterating over every element of the inner array, but just one - first element of the first array, second element of the second array etc.
QUESTION
I have a react app that has a NavBar and a grid system. This NavBar shows some information and has buttons to run the application and the grid system contains the functions and visualizes the application. I want to have the NavBar button click trigger a function to call in the grid system component, specifically the animateAlgorithm function. As you can see, I already have a provider that shares some state information between these two components. What I don't understand is how to make it call the function.

...ANSWER
Answered 2021-Jun-11 at 18:53What you need to do is use the useImperativeHandle
, so you can access the function from outside of your component.
First, call useRef
to create a reference and pass it to your GridContainer
as prop, we will handle the ref
later inside the component using fowardRef
. Then, you need to wrap the animateAlgorithm
inside a handler function and use it as props in NavBar
so you call it when the button is clicked.

QUESTION
I'm using AWS QuickSight to build a dashboard with analytics and metrics related to the usage of a system. I'm trying to visualize user's registration over time. I've created a parameter and control on my dashboard that allows the dashboard user to select 'Last N days' (7, 30, 60, 90, 180, 365 days), and I have an associated line chart that will plot the related data.
However the issue is that there are some days where no user's registered, and that leaves gaps of seemingly unreported data (in the line chart). What I would like to do is JOIN
my current query on day
with a query that returns a single field each row containing the last 365 days.

Based on the guide Implementing PCA in Python, by Sebastian Raschka I am building the PCA algorithm from scratch for my research purpose. The class definition is:
...ANSWER
Answered 2021-Jun-11 at 12:52When calculating an eigenvector you may change its sign and the solution will also be a valid one.
So any PCA axis can be reversed and the solution will be valid.
Nevertheless, you may wish to impose a positive correlation of a PCA axis with one of the original variables in the dataset, inverting the axis if needed.

QUESTION
I'm coding a complex chart in SwiftUI that the user can scroll horizontally to see past data points.
The chart holds quite a few subviews inside so I would like to debug performance while scrolling.
Can anyone tell me how can I visualize current FPS (frames per second) when debugging my SwiftUI app. I've tried Instruments but can't seem to find anything related to displaying fps with SwiftUI.
Can anyone point me in the right direction? Thanks!
...ANSWER
Answered 2021-Jun-11 at 07:31Since SwiftUI uses Core Animation for rendering, you can measure the FPS by profiling and using 'Core Animation FPS' instrument.
Other than that, you can check out here for a great tutorial about the SwiftUI specific Instrument, for identifiying slow layouts.
Make sure you are using a real device for that, because Core Animation FPS Instrument will not work with a simulator.
