Write a function called loopCompare that takes in two arrays
     Write a function called loopCompare that takes in two arrays. XValues and YValues. It should return an output array, ZValues. This function should use a loop with a conditional statement inside of it to implement the following: When XValues(i) > YValues(i), ZValues(i) - XValues(i)  When XValues(i) - 
  
  Solution
function ZValues = loopCompare(XValues, YValues)
    n = length(XValues);
    ZValues = zeros(1, n);
    for i = 1:n
        if(XValues(i) > YValues(i))
            ZValues(i) = XValues(i);
        else
            ZValues(i) = YValues(i);
        end
    end
 end
