Note

Since this problem handles UTF8 strings, it may be difficult to solve in some languages.

Problem Statement

Alice: "So just nowｗ I was rereading the stuff I wroteｗ and I got curious about what cracked me up the mostｗ so I tried writing a programｗｗｗ"

Bob: "Thatｗｗ I'm super curiousｗ"

Carol: "I am curious as well."

Output the sentence immediately before the longest run of consecutive "ｗ" (note that this is a full-width character).
However, a run of "ｗ" at the beginning of the line is not counted as such a location.

The sentence ends at the character immediately before the longest run of "ｗ".
It starts where, counting from the end of the sentence toward the beginning, the next "ｗ" is about to be reached, or at the beginning of the line if no "ｗ" appears.
If there are two or more longest runs of "ｗ", separate the sentences with newlines. (Output them in order of appearance.)
If "ｗ" never appears, or if all characters are "ｗ", output an empty string.

Input

S

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

Output

Output the UTF8 string (without BOM) that satisfies the problem statement.
(You normally should not need to worry about this, but if a BOM is attached, the verdict will be WA.)
Print a newline at the end.

Sample

Sample 1
Input
海賊王にｗ俺はなるｗｗ
Output
俺はなる

The run of 2 "ｗ" is the longest, so output the sentence before it.

Sample 2
Input
うはｗｗｗｗｗおｋｗｗｗｗｗ
Output
うは
おｋ

There are two longest runs of "ｗ", so output both sentences.

Sample 3
Input
ｗｗそれなｗｗ
Output
それな

Ignore the "ｗ" at the beginning of the line.
