<p>Hey guys. I’ve been reading this for a while, and I just created an account to start voicing my own concerns. But first, can somebody link me the answers to the FR? I know they were posted here but I forgot on which page.</p>
<p>My biggest concern is on skyview.</p>
<p>I declared a boolean and set it to true. If it were true, then numbers would be added to the right. If it were false, numbers would be added into the array to the left. </p>
<p>I then said an if statement something along the lines of </p>
<p>if (forward && (index of current value) == the # columns of the array) then forward = !forward, row++; and then the code would start adding in numbers to the right. Whenever boolean forward was true, add values to the right, if not true, add the to the left. </p>
<p>I saw some people use the modulus method. I think that was also the correct way to solve the problem on the website with the answers.</p>
<p>Could I potentially be taken points off for it?</p>
<p>Second Concern:</p>
<p>The GridWorld Free response. I know it said “must not violate post conditions” but, in the example, it also showed the bug disappearing when there were no more move spaces. Because of that, I added in removeselffromgrid(), but that’s wrong? If so, does it inhereited code automatically remove itself, so that you don’t need to?</p>
