Little A is one member of ACM team. He had just won the gold in World Final. To celebrate, he decided to invite all to have one meal. As bowl, knife
and other tableware is not enough in the kitchen, Little A goes to take backup tableware in warehouse. There are many boxes in warehouse, one box contains only one thing, and each box is marked by the name of things inside it. For example, if "basketball"
is written on the box, which means the box contains only basketball. With these marks, Little A wants to find out the tableware easily. So, the problem for you is to help him, find out all the tableware from all boxes in the warehouse.
For each test of the input, output all the name of tableware.
The tableware only contains: bowl, knife, fork and chopsticks.

题目意思非常easy，就是输入n个字符串。当遇到bowl, knife, fork ，chopsticks.这四个字符串时就输出。
所有在一行输出。每两个中间用一个空格隔开，最后不能有空格（我原以为没关系，所以在这里PE了一次…这就是教训啊…）。。
