Define the following function

Given the value C of F(p1, p2 ... pn), can you find the minimum and maximum value of F(q1, q2 ... qn)?

The input contains several test cases. For each test case, it contains three lines.

Line 1: two integers n (1<= n <= 50000) and C.
Line 2: n integers p1, p2 ... pn (|pi| < 1000 for 1 <= i <= n).
Line 3: n integers q1, q2 ... qn (|qi| < 1000 for 1 <= i <= n).

For each test case, output the minimum and maximum value in a single line with the fraction rounded to 3 decimal places.
