acm中的Catching Fish的X与Y代表什么,还有整个题意是什么意思,那位大大帮帮忙啊,
Problem Description
Ignatius likes catching fish very much.He has a fishnet whose shape is a circle of radius one.Now he is about to use his fishnet to catch fish.All the fish are in the lake,and we assume all the fish will not move when Ignatius catching them.Now Ignatius wants to know how many fish he can catch by using his fishnet once.We assume that the fish can be regard as a point.So now the problem is how many points can be enclosed by a circle of radius one.
Note:If a fish is just on the border of the fishnet,it is also caught by Ignatius.
Input
The input contains several test cases.The first line of the input is a single integer T which is the number of test cases.T test cases follow.
Each test case starts with a positive integer N(1

问题描述
伊格很喜欢捕鱼.他有一个渔网,其形状是一个半径为一循环.现在,他即将使用他的渔网捕鱼.所有的鱼在湖中,我们假设所有的鱼不会移动时,伊格赶上他们.现在伊格想知道有多少鱼,他可以用他的渔网捕捉一次.我们假设,这些鱼可以作为一个点方面.所以,现在的问题是有多少点可以由一个半径为1圈包围.
注:如果只是一条鱼的渔网的边界,它也是引起了伊格.
输入
输入包含多个测试案例.另外,输入的第一行是一个整数T较差的测试个案.T检验的个案跟进.
每个测试案例与一正整数N(1
