# Innohorse

In Innokingdom there are special horses for chess knights, innohorses. Each innohorse is represented by a pair of integers (**x**, **y**), **0** ≤ **x** ≤ **y**. Innohorse moves in the following way: first it moves **x** cells in one of the four general directions, then turns **90** degrees to the left or to the right, then finally moves **y** more cells. For instance, an ordinary chess knight horse is an innohorse of type (**1**, **2**).

Alex and Jane has just seen one innohorse, it jumped from cell **A** to cell **B**. They wonder what is the type of this innohorse. Help them answer this question.

#### Input

Chessboard consists of **8** rows and **8** columns. Rows are assigned integers from **1** to **8**, and columns are assigned letters from '**a**' to '**h**'. So every cell is represented by a pair of a letter and a digit.

Two lines consist of descriptions of cells **A** and **B** respectively.

#### Output

Print two integers **x** and **y** (**0** ≤ **x** ≤ **y**), representing the type of innohorse.
