B'The closing ceremony of Squanch Code Cup is held in the big hall with n xe2 x80 x89 xc3 x97 xe2 x80 x89m seats, arranged in n rows, m seats in a row. Each seat has two coordinates (x, xe2 x80 x89y) (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89x xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n, 1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89y xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89m). There are two queues of people waiting to enter the hall: k people are standing at (0, xe2 x80 x890) and n xc2 xb7m xe2 x80 x89- xe2 x80 x89k people are standing at (0, xe2 x80 x89m xe2 x80 x89+ xe2 x80 x891). Each person should have a ticket for a specific seat. If person p at (x, xe2 x80 x89y) has ticket for seat (xp, xe2 x80 x89yp) then he should walk |x xe2 x80 x89- xe2 x80 x89xp| xe2 x80 x89+ xe2 x80 x89|y xe2 x80 x89- xe2 x80 x89yp| to get to his seat. Each person has a stamina -- the maximum distance, that the person agrees to walk. You should find out if this is possible to distribute all n xc2 xb7m tickets in such a way that each person has enough stamina to get to their seat. The first line of input contains two integers n and m (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xc2 xb7m xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89104) -- the size of the hall. The second line contains several integers. The first integer k (0 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89k xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xc2 xb7m) -- the number of people at (0, xe2 x80 x890). The following k integers indicate stamina of each person there. The third line also contains several integers. The first integer l (l xe2 x80 x89= xe2 x80 x89n xc2 xb7m xe2 x80 x89- xe2 x80 x89k) -- the number of people at (0, xe2 x80 x89m xe2 x80 x89+ xe2 x80 x891). The following l integers indicate stamina of each person there. The stamina of the person is a positive integer less that or equal to n xe2 x80 x89+ xe2 x80 x89m. If it is possible to distribute tickets between people in the described manner print "YES", otherwise print "NO". '...
