Descr iption

在平面上的n个点中找出横坐标最小的点。

Input

第一行是一个正整数n（1<=n<=1000），表示一共有n个点。

接下来n行，每行2个整数，分别表示每个点的横坐标和纵坐标。

Output

输出横坐标最小的那个点的横坐标和纵坐标，如果横坐标最小的点有多个，则只输出其中纵坐标最小的那个点。

N points on the plane to find the abscissa of the minimum point.

Input

The first line is a positive integer n (1 <= n <= 1000), said a total of n points.

The next n lines, each line two integers that represent horizontal and vertical coordinates of each point.

Output
