220 - Midpoint


Time Limit: 1 sec


The Problem

  • Any point in 2-D may be located by an ordered pair (x, y).
  • The x-coordinate, x, is the value on the x-axis vertically above or below the point.
  • The y-coordinate, y, is the value on the y-axis horizontally right or left of the point.

Make a simple program that reads 4 variables named x1, y1 and x2, y2 which are represent two points (x1, y1) and (x2, y2). You task is to find the midpoint between 2 given points (x1, y1) and(x2, y2).



The Input

The input file contains 4 integer numbers x1, y1x2, and y2 (x1, y1x2, y2 < 1000).


The Output

Output will show two intiger values seperated by space which represend the midpoint in a separate line.
