A - Accountant notes

Time limit: 16 s
Memory limit: 200 MB

You had an accountant, who recorded all your expenses. Each day you sent her notes on expenses and she appended them to a single big summary file. Each of your notes consisted of several rows, like the following:

bed = 100
table = 150
furniture = bed + table
furniture = furniture + 10

which (probably) meant that you spent 250 on furniture and 10 on transport (probably). More generally, each row in your note was one of the following:

name = number
name = item + item

where item was either number or name, number was a natural number not exceeding (with no leading zeroes) and name was an arbitrary sequence of small and capital letters.

While transferring your notes to the summary file, the accountant neither changed the order of rows of a note nor shuffled rows of different notes. But sometimes she changed names... She did it consistently though, changing all occurrences of the name in a single note to the same new one. Also, different names from the same note were rewrivaren as different names in the summary file. But there is no guarantee that it was consistent with your other notes — the name beer from one note could have been rewrivaren as drink, the name tee from the other note could have been rewrivaren as drink as well, while the beer from the next note could have been rewrivaren as food. Lets call her version of your note a transcription of it.

The problem is that your accountant has just quit (and, as it turned out, took most of your savings) and you are left with the summary file and a huge unsorted pile of notes. You want to check if it is possible that some of your notes were not recorded in the summary, so for each note you are searching for a piece of summary that can be its transcription.

Multiple Test Cases

The input contains several test cases. The first line of the input contains a positive integer , denoting the number of test cases. Then test cases follow, each conforming to the format described in section Single Instance Input. For each test case, your program has to write an output conforming to the format described in section Single Instance Output.

Single Instance Input

The first line of an input instance contains an integer , the number of notes (). The following lines first contain the descriptions of notes, then the description of the summary file follows. The description of each note and the summary starts with a line consisting of a single integer (). Then lines follow, each containing a single row of a note or the summary. The format of each row is as described in the problem statement above. You can assume that names, numbers, signs "=" and "+" are separated by single spaces and each line is at most characters long. Both the length of the text and the sum of all patterns lengths will be at most .

Single Instance Output

The output for a single instance should consist of lines. In the -th line there should be the answer for the -th note. It should be the number of the first row in the summary file, where a possible transcription of the -th note starts (the first row of the summary file has number ) or word NONE if no fragment of the summary file could be such possible transcription.
