In the Che region, in each of
N districts, it was decided to sow free fields with wheat. After the harvest, all the wheat is taken to the store and counted how much was harvested in each area. Known area planted with wheat (
Ai, in hectares) in each district, and the amount harvested in each district (
Bi, < /sub>in centners). Write a program that calculates the average wheat yield for each district and for the entire region.
Input
In the first line, enter the value
N - the number of districts in the region (1 <= N <= 1000). In the second line, enter
N numbers
Ai - area of each district (1 <= A
i <= 10
9). In the second line ,
N numbers
Bi is entered - the yield of each region (1 <= B
i < = 10
9).
Imprint
Output in the first line, separated by a space, the average yield for each district, rounded to 6 decimal places. In the second line, output the average yield for the region as a whole, rounded to 6 decimal places.
