I am working on a React Web Application Where I fetch and display student data from an API and I keep getting the error,

Warning: Each child in a list should have a unique "key" prop. Check the render method of Accordion

Accordion.js being one of my components of my Web Application

Any Help to fix this issue would be appreciated :)

I have tried passing a key prop with an id to the Accordion component from a parent component, but that did not seem to work. Could it be that I need to pass a key in my test score paragraph?

Replace values from a column based on the following rule: t0345_0400_d2 = 03:45, or to keep only the first part of the value in time format. How can I do this?

Data structure:

Output:

Sample data:

I wanted to insert my data to a specific sheet name based on form input value of "svdate":

I was reading this code (source):

I am doing this graph with this code

I need to retrieve a range delimited by indexes from a specific array

I cannot use OFFSET because it doesnt use an array as a parameter. And the range will then be use for a secondary calculation

The example:

I want to calculate the SUM of the 4th to the 11th value in the column Numbers.

So at the end the formula should look something like: =SUM(Numbers[4:10]) = 36 4 and 10 being the desired indexes.

I tried with OFFSET and INDEX but cant figure out how to do it.

I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.

And manifest.

uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

is written.

Please let me know the solution. And this content is written with a translator, so the sentence can be strange.

when you press finButton, the logcat is shown below.

The code corresponding to the 116th line is this.

FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

I'm trying to decrease the bundle size of my Vue project, which scaffolded by the vue-cli, by using CDN of firebase, Vue, and Vuetify.

So, I've added links of these CDN in public/index.html as follow:
