输入的第一行是一个正整数，表示多少个数据集将包括（N）。每个随后的N线将包含X和弗雷德正在考虑土地y笛卡尔坐标。这些将漂浮在距离来确定点数。的Y坐标将是非负数。 （0,0）将不给出。对于每一个数据集，输出的一个行应出现。此行应采取的形式为：“房产N：这个属性将开始削弱在一年Z.”，其中n是数据集（从1算起），和Z是第一年（从1开始）此属性将在半圆AT年Z. Z中的一端必须是整数。最后的数据集之后，这应该打印出“END的输出。”-The first line of input will be a positive integer indicating how many data sets will be included (N). Each of the next N lines will contain the X and Y Cartesian coordinates of the land Fred is considering. These will be floating point numbers measured in miles. The Y coordinate will be non-negative. (0,0) will not be given.

For each data set, a single line of output should appear. This line should take the form of: “Property N: This property will begin eroding in year Z.” Where N is the data set (counting　1), and Z is the first year (start　1) this property will be within the semicircle AT THE END OF YEAR Z. Z must be an integer. After the last data set, this should print out “END OF OUTPUT.”
