Problem descriptionpaper quality and quantity have long been used to measure a Research's scientific productivity and scientific impact. citation, which is the total times a paper has been cited, is a common means to judge importance of a paper. however, with all these factors varying, a collegiate committee has problems when judging which research is doing better. for this reason, H-index is proposed and now widely used to combine the above factors and give accurate judgement. h-index is defined:
A scientist has index H If H of [his] NP papers have at least H citations each, and the other (NP-h) papers have at most h citations each.
In other words, a scholar with an index of H has published H papers each of which has been cited by others at least H times. note that H-index is always an integer. it's said that achiveing H-index of 18 means one is fully quality to be a memory SOR, and H-index of 45 or higher cocould mean membership in the united states Emy of sciences.
You are to calculate the H-index for all the researchers in the list, base on the given information. inputthere are multiple scenarios in the input, terminated by a single zero (0 ).
Each of the scenarios begin with an integer N (1 <= n <= 100), means that there are n papers. n lines follow, each contain a string (not exceeding 20 characters long), representing the author of the corresponding paper, without white spaces in-. though it wocould be common for one paper written by several authors, there wocould be exactly one author of each of these papers. finally, there are n lines of strings, containing '0's and '1' S. if the J-th character in the I-th line is '1', it means the I-th paper cites the J-th paper. A paper cocould never cite itself. outputfor each scenario, output as same lines as the number of authors given. each line contains the author's name and his h-index. the list shoshould be sorted first by H-index in descending order, than by name in alphabetic order (actually, ASCII order. so 'B' is prior to 'A ').
Output a blank line after each scenario. sample input
