题目描述

You are given nn patterns p1,p2,,pnp_1, p_2, \dots, p_n and mm strings s1,s2,,sms_1, s_2, \dots, s_m . Each pattern pip_i consists of kk characters that are either lowercase Latin letters or wildcard characters (denoted by underscores). All patterns are pairwise distinct. Each string sjs_j consists of kk lowercase Latin letters.

A string aa matches a pattern bb if for each ii from 11 to kk either bib_i is a wildcard character or bi=aib_i=a_i .

You are asked to rearrange the patterns in such a way that the first pattern the jj -th string matches is p[mtj]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.

输入格式

The first line contains three integers nn , mm and kk ( 1n,m1051 \le n, m \le 10^5 , 1k41 \le k \le 4 ) — the number of patterns, the number of strings and the length of each pattern and string.

Each of the next nn lines contains a pattern — kk characters that are either lowercase Latin letters or underscores. All patterns are pairwise distinct.

Each of the next mm lines contains a string — kk lowercase Latin letters, and an integer mtmt ( 1mtn1 \le mt \le n ) — the index of the first pattern the corresponding string should match.

输出格式

Print "NO" if there is no way to rearrange the patterns in such a way that the first pattern that the jj -th string matches is p[mtj]p[mt_j] .

Otherwise, print "YES" in the first line. The second line should contain nn distinct integers from 11 to nn — the order of the patterns. If there are multiple answers, print any of them.

说明/提示

The order of patterns after the rearrangement in the first example is the following:

  • aaaa
  • __b_
  • ab__
  • _bcd
  • _b_d

Thus, the first string matches patterns ab__, _bcd, _b_d in that order, the first of them is ab__, that is indeed p[4]p[4] . The second string matches __b_ and ab__, the first of them is __b_, that is p[2]p[2] . The last string matches _bcd and _b_d, the first of them is _bcd, that is p[5]p[5] .

The answer to that test is not unique, other valid orders also exist.

In the second example cba doesn't match __c, thus, no valid order exists.

In the third example the order (a_, _b) makes both strings match pattern 11 first and the order (_b, a_) makes both strings match pattern 22 first. Thus, there is no order that produces the result 11 and 22 .
