A pincode consists of N integers between 1 and 9. In a valid pincode, no integer is allowed to repeat consecutively. For example, 1, 4, 5, 5, 6, 7 is invalid because 5 occurs twice. I tested the example but it does not outputs what the example shows. Any suggestions.

Insert code or attach the m-file. Make it easy for people to help you, not hard.

Hi Jose,
Check if the following code works for you:-
function [repPos, pinCodeFix] = pinCodeCheck(pinCode)
repPos = [];
pinCodeFix = [pinCode(1)];
for i=2:length(pinCode)
if pinCode(i-1) == pinCode(i)
repPos = [repPos i];
else
pinCodeFix = [pinCodeFix pinCode(i)];
end
end
end
Produces the output as:-
repPos =
3 5
pinCodeFix =
2 9 5 3

function [repPos, pinCodeFix] = pinCodeCheck(pinCode)
lo = [true;diff(pinCode(:)) ~= 0];
repPos = find(~lo);
pinCodeFix = pinCode(lo);
end

i don't think we are supposed to have learned any of that yet, if we are going in order of what we've learned how to impliment in the chapters, (and this homework requires using arrays which arent taught until the next chapter anyway, to the professor made these extra credit) all we are supposed to use is loops, arrays, and branches
