You are an elementary school student and you have been asked
to solve a bunch of simple problems. You have to report your
results in a nice pretty table. Of course, being a budding
computer scientists, you are not going to solve these problems
yourself; you are going to get a machine to do it for you.
Input
Input consists of up to 100 test cases. Each starts with a
number $1 \leq n \leq 50$
giving the number of math problems in the test case. The next
$n$ lines each contain a
math problem of the form $x +
y$, $x  y$ or
$x * y$. All values for
$x$ and $y$ are integers in the range
$[10000,10000]$. The end
of all test cases is marked with a value of zero for
$n$.
Output
For each test case, print a table of the results, with
individual values right justified in their fields. Your results
should be printed in row major order with a single space
between each pair of adjacent output columns. The number of
columns should be chosen to be as large as possible without
exceeding a line length of 50 characters. All field widths
within a test case should be the same and should be chosen to
be large enough to accommodate the longest result in the table.
Do not print any trailing spaces. Output one blank line between
the the outputs for adjacent test cases.
