Reasoning 1
Question: There is a well that is sixteen meters deep. A frog falls into it. This frog can jump two meters at a time, but because of the slippery well wall, it will slide down one meter. After jumping five times, it feels exhausted and rests, during which it slides down three meters. How many jumps does it need to get out?\ Later, when it is almost at the top, there is a ring around the well opening that extends inward and is parallel, so it cannot jump out directly (as shown in the picture).\ Note: This problem is very difficult, so if someone solves it, in addition to the original reward from the reasoning team, I will award an extra 100,000. But it only counts if the entire solution is correct.
