Two people play a game: report the number in turn, the number reported cannot exceed 8 (nor can it be 0), add up the numbers reported by the two people, and whoever reports the number will add up to 88 (or 88 above), whoever wins. If you are asked to report first, you will definitely win, so how much should you report for the first number.
两人做一种游戏：轮流报数，报出的数不能超过8(也不能是0)，把两个人报出的数连加起来，谁报数后，加起来的数是88(或88以上的数)，谁就获胜．如果让你先报，就一定会赢，那么你第一个数应该报多少．
