( 2414 ) E Pattern Matching PROGRAMMING bitmasks data structures dfs and similar graphs sortings strings

B'You are given n patterns p_1, p_2, ... , p_n and m strings s_1, s_2, ... , s_m . Each pattern p_i consists of k characters that are either lowercase Latin letters or wildcard characters (denoted by underscores). All patterns are pairwise distinct. Each string s_j consists of k lowercase Latin letters. A string a matches a pattern b if for each i from 1 to k either b_i is a wildcard character or b_i=a_i . You are asked to rearrange the patterns in such a way that the first pattern the j -th string matches is p[mt_j] . You are allowed to leave the order of the patterns unchanged. Can you perform such a rearrangement? If you can, then print any valid order. The first line contains three integers n , m and k ( 1 <= n, m <= 10^5 , 1 <= k <= 4 ) -- the number of patterns, the number of strings and the length of each pattern and string. Each of the next n lines contains a pattern -- k characters that are either lowercase Latin letters or underscores. All patterns are pairwise distinct. Each of the next m lines contains a string -- k lowercase Latin letters, and an integer mt ( 1 <= mt <= n ) -- the index of the first pattern the corresponding string should match. Print "NO" if there is no way to rearrange the patterns in such a way that the first pattern that the j -th string matches is p[mt_j] . Otherwise, print "YES" in the first line. The second line should contain n distinct integers from 1 to n -- the order of the patterns. If there are multiple answers, print any of them. The order of patterns after the rearrangement in the first example is the following: Thus, the first string matches patterns ab__, _bcd, _b_d in that order, the first of them is ab__, that is indeed p[4] . The second string matches __b_ and ab__, the first of them is __b_, that is $$'...
