215. Roll-call in Woop Woop High


Problem Statement:
The new principal of Woop Woop High is not satisfied with her pupils performance.
She introduced a new roll-call process to get a daily measure of the pupils' learning,
which proceeds as follows:

At the beginning of the daily roll-call period each pupil is handed a question, which
they must attempt to answer, before proceeding to their classes. A pupil stops after the
question is answered correctly. Each pupil is allowed up to five attempts to answer the
question correctly.

Pupils who answer correctly on the first attempt are marked present. Pupils who
answer correctly after more than one attempt are encouraged to work at home. Pupils
who fail to develop a correct answer within five attempts are given remedial classes
after school. Pupils who do not give any answer are marked as abscent.

Your task is to write a program that reads the pupils' assessments and generates
performance reports for the principal to proceed with appropriate actions.


Input Format:
The input starts with an integer K (1 <= K <= 100) indicating the number of classes.
Each class starts with an integer N (1 <= N <= 50) indicating the number of pupils in
the class. Each of the following N lines starts with a pupil's name followed by up-to
five assessments of his/her answers. An assessment of 'yes' or 'y' indicates a correct
answer and an assessment of 'n' or 'no' indicates a wrong answer. A pupil's name
consists of a single string with no white spaces.


Output Format:
The attendance report for each class consists of five lines.
- The first line consists of the sentence: "Roll-call: X", where X indicates the class
number starting with the value of one.
- The second line consists of the sentence: ''Present: Y1 out of N'', where Y1 is the
number of pupils who did not submit a wrong answer.
- The third line consists of the sentence: ''Needs to study at home: Y2 out of N'', where
Y2 is the number of pupils who submitted a number of wrong answers before
submitting the correct answer.
- The fourth line consists of the sentence: ''Needs remedial work after school: Y3 out of
N'', where Y3 indicates the number of pupils whose submitted five wrong answers.
- The fifth line consists of the sentence: ''Absent: Y4 out of N'', where Y4 indicates the
number of absent pupils.
