Creating a program that guesses the colours( not a colour)??

I am currently stuck at task 4 at checking how many colours the user entered are correct, and the colour and position are correct! I've tried so hard. Please don't say that I did not make an attempt. And is my false condition correct for breaking the loop? Thanks I am new to MATLAB.

% Initiate Random Color Sequence
% r-red; b-blue; y-yellow; g-green; w-white; p-purple; o-orange;
all_colors = 'rbygwpo';
index = randperm(7);
hidden_seq = all_colors(index(1:5));
count = 0;
while 1
    %Prompting user to enter input
    result = input('Guess the 5 characters colour sequence: ');
    count = count + 1;       

    %Validate user input
    if numel(result) > 5 || numel(result) < 5
        error('You have entered more or less than 5 characters')
    end

    %Check the user guesses
    % 1. How many guesses has correct colors and position?
    % 2. How many guesses has correct colors?
    result == hidden_seq
end

Close, but you need to sum your comparison to get the count of the number in the right location, and you can use ismember() to find the number of correct colors even if they're in the wrong location:

count = 0;

  %Prompting user to enter input

    break;

  count = count + 1;
  % Get rid of any spaces they may have entered
  result(result == ' ') = [];
  
  %Validate user input
  if numel(result) > 5 || numel(result) < 5
    uiwait(warndlg('You have entered more or less than 5 characters'));

  % 2. How many guesses are the correct colors (regardless of location)?
  ia = ismember(unique(result), hidden_seq)
  numColorMatches = sum(.....
end

|how do you sum up the terms?|what built in function should i use thanks

[Image Analyst]

There is a sum() function that is built-in. Look it up in the help.

[Natalia Wong]

is it sum(matches)? and if the guesses are fully correct, how should i print congratulations, you got the correct guess with the correct colours printed below. If not all the guesses are correct, how do I direct the user back to the input? Thanks

    numColorMatches = sum(ia);

    if numColorsInCorrectLocation = '5
    fprintf( 'Congratulation! You got the correct colour sequence: \n', hidden_seq)

end now i'm having problems with the last few lines of my program can you pls help me out thanks Image Analyst

[Image Analyst]

Don't use an apostrophe before the 5 and you need an "end" for the "if" and you need a %s in the format string if you're going to print out the hidden_seq variable.

if numColorsInCorrectLocation = 5
    fprintf( 'Congratulation! You got the correct colour sequence: %s\n', hidden_seq);
end

Since this is an assignment, I'll just give a hint. If you remove the exact matches from both (a copy of) the guess and (a copy of) the right answer and have 2 blue, 1 red, and 1 yellow left in your guess and 1 blue, 2 red, and 1 green left in your correct answer, how many "right color, wrong location" entries do you have? How did you figure that out? Can you automate that process?
