Problem

In this challenge, we practice calculating Spearman's rank correlation coefficient.

Task

Given two n-element data sets, X and Y, calculate the value of the Spearman's rank correlation coefficient.

Input Format

The first line contains an integer, n, denoting the size of data sets X and Y.
The second line contains n space-separated real numbers (scaled to at most one decimal place), defining data set X.
The third line contains n space-separated real numbers (scaled to at most one decimal place), defining data set Y.

Output Format

Print the value of the Spearman's rank correlation coefficient, rounded to a scale of 3 decimal places.
