How come test case number 9 in my submission has failed? Doesn't the caterpillar slip below ground level the first night and then catch the apple the next day. In the first day he is at height 801 cm but then at night he drops 1188cm (which would put him below ground). Could someone please explain why my assumption is wrong?
