Bring out the areas in decreasing order.

**Input**

The first line contains one number **N** - the number of columns (**N** = **4**..**10000**), then **N** rows in which to record their tselochiselnye coordinates such that the module does not exceed **10 ^{9}**.

**Output**

In decreasing order of two numbers with an accuracy of **10 ^{-2}** - the area separated sites.
