Description

    约翰想要计算他那N(1≤N≤1000)只奶牛的名字的能量．每只奶牛的名字由不超过1000个字待构成，没有一个名字是空字体串，  约翰有一张“能量字符串表”，上面有M(1≤M≤100)个代表能量的字符串．每个字符串由不超过30个字体构成，同样不存在空字符串．一个奶牛的名字蕴含多少个能量字符串，这个名字就有多少能量．所谓“蕴含”，是指某个能量字符串的所有字符都在名字串中按顺序出现（不一定一个紧接着一个）．

    所有的大写字母和小写字母都是等价的．比如，在贝茜的名字“Bessie”里，蕴含有“Be”

“sI”“EE”以及“Es”等等字符串，但不蕴含“lS”或“eB”．请帮约翰计算他的奶牛的名字的能量．

Input

    第1行输入两个整数N和M，之后N行每行输入一个奶牛的名字，之后M行每行输入一个能量字符串．

Output

 

    一共N行，每行一个整数，依次表示一个名字的能量．

Sample Input

5 3
Bessie
Jonathan
Montgomery
Alicia
Angola
se
nGo
Ont

INPUT DETAILS:

There are 5 cows, and their names are "Bessie", "Jonathan",
"Montgomery", "Alicia", and "Angola". The 3 good strings are "se",
"nGo", and "Ont".

Sample Output

1
1
2
0
1

OUTPUT DETAILS:

"Bessie" contains "se", "Jonathan" contains "Ont", "Montgomery" contains
both "nGo" and "Ont", Alicia contains none of the good strings, and
"Angola" contains "nGo".
