QUESTION 1. Create a function sumcomp that compares the sum of all the odd-indexed elements with the sum of all the even-indexed elements and returns:

0, if they are equal,

1, if the sum of the odd-indexed elements is greater,

2, if the sum of the even-indexed elements is greater

Answer 1

function result = sumcomp(lst)
    oddSum = 0;
    evenSum =0;
    result =0;
    for i=1:length(lst)
        if(mod(i,2) == 0)
            evenSum = evenSum + lst(i);
        else
            oddSum = oddSum + lst(i);
        end
    end
    if(oddSum == evenSum)
        result = 0;
    elseif(oddSum > evenSum)
        result = 1;
    else
        result = 2;
    end
end
