题目描述

The first line contains integer $n$ $(2<=n<=1000)$ . The next line contains the sequence of integers $a_{1},a_{2},...,a_{n}$ $(1<=a_{i}<=1000)$ . It is guaranteed that the sum of all $a_{i}$ doesn't exceed $1000$ .

输入格式

Print $max |y_{i}-y_{j}|$ lines (where $y_{k}$ is the $y$ coordinate of the $k$ -th point of the polyline), in each line print characters. Each character must equal either « $/$ » (slash), « $$ » (backslash), « » (space). The printed image must be the image of the given polyline. Please study the test samples for better understanding of how to print a cardiogram.

Note that in this problem the checker checks your answer taking spaces into consideration. Do not print any extra characters. Remember that the wrong answer to the first pretest doesn't give you a penalty.
