Pasquale’s Tryangle
Quite possibly
one of the most unfamous mathematicians of all time, Pasquale had his own interests.
Most of his contemporaries considered him to be a bit eccentric and not
completely useful. His great, great grandson is attempting to prove that there
are indeed useful applications of his ancestor's research. Recently, Young Elonzo Pasquale discovered an old notebook containing many
notes on a mathematical construct described as 'Pasquale's Tryangle'. Elonzo hopes to
analyze the results of several of Pasquale's Tryangles
in order to figure out what they are good for and to prove that his great, great
grandfather was a worthwhile mathematician.
Elonzo has requested that we help him out by
writing a program that can calculate the results of a series of Pasquale's Tryangles. A Pasquale Tryangle
starts with a series of 2 or more integer numbers. The numbers in the row are added from right
to left and the partial sum is written beneath each number in that row (forming
a new row below). Since the rightmost sum is merely the sum of the last number
itself, it is not considered a 'true' sum (a true sum should have at least two
numbers to add together), and is therefore dropped. These steps are repeated
until a row with a single number is arrived at. This final number is referred
to as the 'point' of that Pasquale Tryangle.
As an example, here's a Pasquale Tryangle of a series of four numbers

Input:
The input will consist of a series of
Pasquale's Tryangles to be 'pointed'. Each line of data will contain a single
integer number. The first line will be the number of Pasquale's Tryangles to be 'pointed'. The next line will be how many
numbers are in the top row of this Tryangle (maximum
of 9 numbers). Next will be the numbers that make up the top line of the Tryangle (one number per line). This sequence (number of
rows followed by the actual numbers) will be repeated for each of the Tryangles.
Output:
For each Pasquale's Tryangle, you are to output a single line with the numeric answer.
