Mahima has been experimenting with a new style of art. She stands in
front of a canvas and, using her brush, flicks drops of paint onto the
canvas. When she thinks she has created a masterpiece, she uses her 3D
printer to print a frame to surround the canvas.

Your job is to help Mahima by determining the coordinates of the
smallest possible rectangular frame such that each drop of paint lies
inside the frame. Points on the frame are not considered inside the
frame.

\(2 \le N \le 100\)
\(X < 100\)
\(Y< 100\)

The first line of input contains the number of drops of paint, \(N\), where \(2 \le N \le 100\) and \(N\) is an
integer. Each of the next \(N\) lines
contain exactly two positive integers \(X\) and \(Y\) separated by one comma (no spaces).
Each of these pairs of integers represents the coordinates of a drop of
paint on the canvas. Assume that \(X < 100\) and \(Y< 100\), and
that there will be at least two distinct points. The coordinates \((0,0)\) represent the bottom-left corner of
the canvas.

For 12 of the 15 available marks, \(X\) and \(Y\) will both be two-digit integers.

Output two lines. Each line must contain exactly two non-negative
integers separated by a single comma (no spaces). The first line
represents the coordinates of the bottom-left corner of the rectangular
frame. The second line represents the coordinates of the top-right
corner of the rectangular frame.
