Problem in "Increasing Automation with Functions > Creating and Calling Functions > (5/5) Create and Call Local Function", Task 1, MatLab Fundamentals

I am currently finishing the course "MatLab Fundamentals" but I cannot reach 100% because in "Increasing Automation with Functions > Creating and Calling Functions > (5/5) Create and Call Local Function", Task 1, I'm not able to answer in the correct way to that Task. Since I thought I answered right, I checked the solution and it was the same as my script; however even copying and pasting the solution script and trying to submit the Task, it appears to be "Incorrect" (Is pp calculated from the function paretoperc?). I can't understand if I'm missing something or if there's some kind of problem since also the solution script doesn't work. What can I do?

Here's the code:

Task 1

ThemeCopy

pp = paretoperc(medals)

Task 2

Further Practice

ThemeCopy

function pp = paretoperc(x)

% Cumulative contribution of data points (in order)

cc = cumsum(sort(x(:),"descend")); % (:) to ensure column vector

cc = 100*cc/cc(end); % Normalize to percentage

% Corresponding percentiles (column vector to match cc)

pct = (1:numel(x))';

pct = 100*pct/numel(pct); % Normalize to percentage

% Find the number of data values needed so that

% P% of the data is in (100-P)% of the values

idx = find(cc >= (100-pct),1,"first");

pp = cc(idx);

end

task2???

[Saivarshini]

use paretoperc to calculate p for the gold medal (stored in golds). store the result in avariable called ppgold???

code for thos task??

I just tested it, and it works for me. Can you share a screenshot of what you are seeing?
