This is a question called 'Draw me until you match me', which was posted this week. Well, since I'm not that good at English, I mistakenly misinterpreted the question that the process is repeated until two same numbers were written down 'in a row'. ex: 2,1,3,5,3,1,'2,2' Well, even after I knew I misinterpreted the question and eventually solved it, I kept wondering whether this problem can be solved. (I had a hard time trying to solve this problem..)
Is there a way to solve this question when we changed the question to the one shown above?
