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.
