    Seens I am first post :)

    I found this problem description tricky and wording could do with improvement.


    original wording

    The first line contains a single integer, q, denoting the number of queries. The subsequent lines describe each query in the following format:

    The first line contains an integer, n, denoting the size of the list.

    Each line of the subsequent lines contains a non-empty string describing ai.


    change above wording to

    A- first line is an int nominating the number (X) of data sets to follow.
    B- 2nd line is an int, nominating the number of n lines of text to follow.
    C- next n lines are text

    repeat B & C X times.

    obvious once spotted. :)
