D. Adding any-D vectors

Problem

Write a program that adds two vectors of any dimension d.

The first line of the input contains the integer d. The remaining d lines each contain 2 integers, the first column is vector 1 and the second column is vector 2.

The output contains vector 1, vector 2 and the result of adding the vectors. The + and = should be on the last line of the output.

Examples

Input

2
1 2
3 4
