说明：  今天TheBeet去门口那家山东煎饼小摊买煎饼，到他付钱的时候他才发现，他的钱包里面只有一张100块。于是他需要把这张100块钱破开，但是TheBeet不喜欢硬币，另外由于某种原因，TheBeet也不喜欢20元的纸币，另外也不喜欢钱包里面有太多张纸币，所以他希望拿到尽量少的纸币数。给出摊主现有的纸币数量，求摊主要如何找零给TheBeet才能满足他的要求。
(Today, Thebeet went to the Shandong pancake stand in front of his door to buy a pancake. When he paid for the pancake, he found that there was only one 100 yuan in his wallet. So he needs to break the $100 bill, but Thebeet doesn't like coins, and for some reason, Thebeet doesn't like the $20 bill, and he doesn't like having too many bills in his wallet, so he wants to get as few as possible. Give the vendor the number of bills he has and ask how the vendor can give change to TheBeet to meet his demand.)
