I am writing some code that takes an array of shapes and finds the average of the array. The concept itself is quite simple but I am having problems. What I did to try to implement the method to find the average is that I used a for loop to add all the values of the array together and then I divided the sum with the number of items in the array. Although I understand how to do this clearly, for some reason I am getting problems. For the equation where I continuously add the previous sum to the new sum, the array gives me an error that says "Expression expected". I am not sure on what that means so I used the IDE fix and it created a new private object for me at the top of the class. Then it gives me another error, it says "Array type expected, java.lang.Object" I was unsure so I decided to import the lang.Object into the file but the error remained the same. How can I fix this?

This is my code below:

I am trying to configure a relationship between to entities in EFCore: Square and Position. Position has one (position) to many (squares) relationship with square named squares, as well as two one - to - one relationship between Square named enPassentTakablePawnOfWhite and enPassentTakablePawnOfBlack. Note that both the FKs as well as the PKs in both of the entities are shadow properties:

The 1 and 3 are id of button and v1 and v3 are id of iframe(youtube emmbedded). i have already used a simple .show() and .hide() but the audio remained of hidden iframe so i am using .remove() and .show(). when i use .remove() the other iframe is gone completely and only iframe remains is of that button which i pressed which i want. however when i press button 3 the removed iframe is not able to load, is there a way to reload it?

the iframes i am using are :-

I want to compile a source code, below error occurred.

cppcleant not found

I searched and found that cppclean must installed with

$ pip install --upgrade cppclean the result is

successfully installed cppclean-0.13 but compile error is steal remained and when I type cppclean result is ** command cppclean not found ** what should I do?

I'm repairing my friend's code and got confused.
My friend wants to fetch entered text (in EditText). Seems easy, right? Well, it is but instead of user input, he gets this warning/error:

To be honest I'm not sure how to fix it. He is coding in Kotlin (Android 10).
Activity that contains EditText:

And XML:

This is how it looks when debugging:

The app started working just fine after running "File -> invalidate Cashes/Restart" option, I just don't understand where this warning came from and how to fix it because the error remained unchanged (even though the app works). Do you have an idea how to solve it?

All the best!

The while loop

I am trying to modify data dict so that only the names within the dictionary which are RSI, MOM is remained within the data dict. How could I create a function that filters and looks for equivalent names in both dicts data and dictionary then delete everything else?

Code:

The problem is a 3 part problem which required me to make a function called addOne that took a number as it's argument and added one to it then create a function called subtractOne that took a number argument and subtracted one from it. After that I had to create a function called usePotions that took a string as it's argument and if the string had the character "A" in it, you would need to use the addOne function on the digit before "A" if it was available. If the string had the character "B" in it, you would need to use the subtractOne function on the digit before the "B" if it was available. You also want to remove the the letters from the string and just return the string with the math performed on the numbers if it was available. This is what I have so far:

I am building a choropleth in D3 v5, but when I tried to load the states' color corresponding with a sequential scale of red, nothing happened and all states remained gray like in this image:

Here is the code that I used for making the map:
