Ascii Art

Statement

Goal

"We don't make mistakes, just happy little accidents." - Bob Ross

While creating mountains in ASCII, you realized that taller mountains could start off from the smaller ones, so why not make some more mountains?

Rules:

- You will be given a list of the heights of mountain peaks along a row.

- The starting height is considered as 0.

- Each step of rise in altitude is represented by '/' and fall by '\'.

- Each peak consists of a rise and fall '/\' at the appropriate height.

- Once a peak has been drawn, proceed either up or down to the next peak. Do not return to 0 between peaks.

- After generating the mountains, end at height 0.

- You may need to draw below 0. Remember, mountains are made from a step lower than their peak. Example, for -1 :

\    /   
 \/\/

which demonstrates the tip of the mountain at -1 height, given that the starting and ending point are at height 0.

This is an extension of "Mountain Map": https://www.codingame.com/ide/puzzle/mountain-map

Input

Line 1: A single integer n representing the number of mountains
Line 2: n, space-separated integers that represent the height of each mountain in sequential order

Output

An ASCII representation of the mountains where each rise in altitude is represented by '/' and fall by '\'.
(Output lines shouldn't contain trailing spaces)

Constraints

0 < n < 15
-15 < height <15

Note: The height must always end at 0.
