Josip used to code in Logo. He loved to draw pictures, but those days are sadly over. Nostalgic, he decided to draw a line that represents the net worth of his company over a period of days.

For each of the days, he knows if the net worth of his company increased by one
unit (represented by `+`

), decreased by one unit (represented by `-`

), or remained
the same (represented by `=`

) during that day. Before the first day, the net worth
was equal to zero.

Josip will draw the line in a big infinite matrix of characters. Indices of matrix rows grow upwards, and indices of columns grow to the right. For the -th day he will draw some character in the -th column.

The character and the index of the row are decided by the following rules:

• If the net worth increased during the -th day, he will draw `/`

in the row with index equal to the
net worth at the beginning of the day.

• If the net worth decreased during the -th day, he will draw `\`

in the row with index equal to the
net worth at the end of the day.

• If the net worth didn't change during the -th day, he will draw `_`

in the row with index equal to
the net worth during the day.

All other cells are filled with `.`

.

Your task is to output the minimal matrix that contains the whole line, i.e. contains all characters `/`

,
`\`

and `_`

that Josip drew.

#### Input

The first line contains an integer , the number of days.

The second line contains a string of characters `+`

, `-`

and `=`

that represents how the company's net
worth changed over the given period.

#### Output

Output the described matrix.

#### Scoring

In test cases worth points the input won't contain the character `-`

.
