Description


Today is Ted's 100th birthday. A few weeks ago, you were selected by the
family to contact all of Ted's descendants and organize a surprise party.
To make this task easier, you created an age-prioritized list of everyone
descended from Ted. Descendants of the same age are listed in dictionary
order.


The only materials you had to aid you were birth certificates. Oddly
enough, these birth certificates were not dated. They simply listed the
father's name, the child's name, and the father's exact age when the baby
was born.

Input Format

Input to this problem will begin with line containing a single integer
n indicating the number of data sets. Each data set will be
formatted according to the following description.


A single data set has 2 components:


  1. Descendant Count - A line containing a single integer X
    (where 0 < X < 100) indicating the number of Ted's
    descendants.

  2. Birth Certificate List - Data for X birth certificates,
    with one certificate's data per line. Each certificate's data will be of
    the format "FNAME CNAME FAGE" where:

    • FNAME is the father's name.
    • CNAME is the child's name.
    • FAGE is the integer age of the father on the date of CNAMEs birth.



Note:


  • Names are unique identifiers of individuals and contain no embedded white
    space.

  • All of Ted's descendants share Ted's birthday. Therefore, the age
    difference between any two is an integer number of years. (For those of you
    that are really picky, assume they were all born at the exact same hour,
    minute, second, etc... of their birth year.)

  • You have a birth certificate for all of Ted's descendants (a complete
    collection).

Output Format

For each data set, there will be X+1 lines of output. The first will
read, "DATASET Y", where Y is 1 for the first data set,
2 for the second, etc. The subsequent X lines constitute your
age-prioritized list of Ted's descendants along with their ages using the
format "NAME AGE". Descendants of the same age will be listed
in dictionary order.
