Description
Coach Fegla has invented a song effectiveness measurement methodology. This methodology in simple English means count the frequency of each character of the English letters [A-Z] in the given song (case insensitive). Get the top 5 characters with the highest frequencies, if 2 characters have the same frequency choose the one which is lexicographically larger. Sum up the indexes of these characters where the index of A is 0, index of B is 1, ..., index of of Z = 25. If this sum exceeds 62 print "Effective"otherwise print "Ineffective"without the quotes.
Input
The first line will be the number of test cases T. Each test case will consist of a series of words consisting only of upper or lower case English letters. Each test case ends with a line containing only "*"without the double quotes. Each word consists of a minimum of 1 letter and a max of 20 letters. The number of words in each test case will be a max of 20,000.
Output
For each test case print a single line containing: Case x: y x is the case number starting from 1. y is is the required answer either "Effective"or "Ineffective"without the quotes.
Sample Input
2 You can be the greatest * You can be the best You can be the King Kong banging on your chest *
Sample Output
Case 1: Effective Case 2: Ineffective
HINT
题意
让你统计频率最高的五个字母，然后看这些字母的值是否超过62
题解：
统计一下就好了……
