Problem Description

2012 If this is the end of the world how to do? I do not know how. But now scientists have found that some stars, who can live, but some people do not fit to live some of the planet. Now scientists want your help, is to determine what all of people can live in these planets.

 

Input

More set of test data, the beginning of each data is n (1 <= n <= 100000), m (1 <= m <= 10) n indicate there n people on the earth, m representatives m planet, planet and people labels are from 0. Here are n lines, each line represents a suitable living conditions of people, each row has m digits, the ith digits is 1, said that a person is fit to live in the ith-planet, or is 0 for this person is not suitable for living in the ith planet.

The last line has m digits, the ith digit ai indicates the ith planet can contain ai people most..

0 <= ai <= 100000

 

Output

Determine whether all people can live up to these stars

If you can output YES, otherwise output NO.

 

Sample Input

1 1 1 1 2 2 1 0 1 0 1 1

 

Sample Output

YES NO

题意：N(N<100,000)个人要去M(M<10)个星球，每个人只可以去一些星球，一个星球最多容纳Ki个人，输出是否所有人都可以选择自己的星球。

 

此题数据绝对很水，我不小心把写成match[][15]这都能过，哈哈哈。

多重匹配转换为最大匹配，把n个容量拆成n个点。
