Uolevi has organized a group vacation to New York. Now people have scattered all over Manhattan and Uolevi is choosing a place to regroup. Manhattan's infrastructure is grid-like: there are vertical and horizontal streets. Uolevi's group has n people numbered 1,2,\dots,n and the i-th person is now at the intersection of roads x_i and y_i. Help Uolevi pick the intersection that minimizes the maximum distance to a person from the group.

Formally, the distance between intersections (a, b) and (c, d) is |a-c| + |b-d|.

Input

The first line contains a single integer n. The i-th of next n following lines contains two integers x_i and y_i.

Output

Print the coordinates of an intersection that minimizes the maximum distance. If there are multiple answers, print any.

Constraints

• 1 \leq n \leq 10^5
• 1 \leq x_i, y_i \leq 10^9
