company pays different hourly wages for different job types. Each week the
company keeps evidence of the total number of work hours for every job type
and the total amount paid to all employees for that week. In different weeks
different job types can be accomplished. The hourly wage for any job type in
the same company remains unchanged. The hourly wage for any job type is a positive
integer and the ratio between the maximum wage and the minimum wage is less
than 20.

You are asked to write a program that computes the hourly wage for every job
type using the data collected a period of time (one or several weeks). The number
of job types is limited to 200 and the number of weeks in one data set is limited
to 50.

The input contains several data sets in text format.

The format for the data set is:

The number of lines for the data set;

information_for__one_or_more_weeks

The format of the information for a week is the following:

job_type1 number_of _hours1

job_type2 number_of _hours2

job_type3 number_of _hours3

����

. total_paid ( the dot marks the ending of info for a week)

The job type is represented as a string of characters (limited to 20). The number
of hours is a positive integer (smaller than 1E5). The total paid is a positive
integer (smaller than 2E10).

The program should write to standard output (for every job type involved in
the data set) a line containing the job type and the hourly wage. The output
for a data set ends with a line containing a dot.

If the program cannot compute a unique hourly wage for every job type it will
print "Incomplete data" and if it cannot compute an integer hourly
wage it will print "Inconsistent data"

An example is given in the following table:

**Input**

job1 6
