H-index因素

Paper 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 as:
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 professor, and H-index of 45 or higher could mean membership in the United States Academy of Sciences.
You are to calculate the H-index for all the researchers in the list, base on the given information.

There 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-between. Though it would be common for one paper written by several authors, there would 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 could never cite itself.

For each scenario, output as many lines as the number of authors given. Each line contains the author‘s name and his H-index. The list should 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.
