Problem Statement

Given a string, output the length of the longest consecutive run of the character "…".

Hint: "…" is not 3 characters.

Beginners are not recommended to solve this in C/C++ (languages in which UTF-8 is hard to handle).

Input

S

A UTF-8 string (without BOM, consisting of printable characters other than newlines) is given as $S$.
The length of the UTF-8 string is at least 1 character and at most 100 characters.

Output

Output the number of "…" in the longest consecutive run. If "…" never appears, output 0. Print a newline at the end.

Sample

Sample 1
Input
……何でもないです。
Output
2

"……" is the longest consecutive run, so the number of "…" in it is 2.

Sample 2
Input
………別に………
Output
3

"………" appears in 2 places, and the number of "…" in either one of them is 3.

Sample 3
Input
……………
Output
5

The number of "…" in "……………" is 5.
