Lily tried several ways to resort the letters (including the space ' ') so that more "good morning"s could be found. The number of "good morning" appeared in a specified string equals the number of positions from which Lily could see a consecutive string "good morning".
With so many letters, Lily is about to be dizzy. She asks you to tell her what is the maximum number of "good morning"s appear in this mail after rearranged in some way.

看题的时候一定要认真地去读题，千万不能略读。

题意：读入一个字符串，重组字符之后，输出字符串中good morning的个数

 

特殊样例：
请理解下面的case
1
ggoooodd(空格)(空格)mmoorrnniinng
这个case要输出2
原因是上面的字母可以重组为
good morningood morning
这样就出现了两个good morning
