Question: Your poor brother again is having trouble with the math professor. Now he is given n points. And, he has to find the smallest rectangle that encapsulates all the points.

Input specification
You will be given an integer in the beginning: the number of points (n). Then, in the following n lines, you will be given (x, y) coordinates of n points where 0 ≤ n ≤ 20,000 and x y coordinates are integers between -3e5 and +3e5.

Output specification:
Show x y coordinates of two corners (lower left corner and upper-right corner).
