You are given N **different** circles , while some region may be covered more than once. If one region is covered by K times, then it was called a "K- Region". So, you are expected to output the area of all the regions! (K from 1 to N)

The first line is one integer n indicates the number of the circles. (1

Output N lines, the i-th line output \[i\] = area\_of\_i\_region here the area must round to 3 digits after decimal point.
