We shall consider sequences that meet the following conditions:
,A single sequence will be called a code.
When two codes are given we estimate their compatibility giving two numbers. The first one (column A in the example) is the sum of those digits that occur in both codes and appear on the same positions in both sequences, whilst the second number (column B) is the sum of those digits that occur in both codes but appear on different positions.
We are given
codes and their compatibility estimations with some
unknown code. One should find and present the unknown code. Sample data and a
result for
are presented below.
| A | B | codes | ||
|---|---|---|---|---|
| 4 | 0 | 4 | 9 | 7 |
| 0 | 10 | 6 | 7 | 4 |
| 0 | 5 | 9 | 4 | 1 |
| unknown code | 4 | 1 | 6 | |
Write a program which:
Your program should read the description from the standard input. In the first
line there is one integer
,
. In the
following
lines there are the descriptions of the given codes of
digits and the estimations of their compatibility with some unknown code, one
per line. In each of the lines there are
non-negative integers
separated by single spaces. The first and the second number are the estimation
of compatibility of the given code with the unknown one, and the last
numbers are different digits from the range of 1-9 forming the
given code.
Your program should write to the standard output. There should be
different digits from the range of 1-9 forming the code to be found, separated
by single spaces.
You may assume that for the test data there is at least one solution. If for the input data there exist many satisfying codes, your program should write out only one of them (arbitrary).
For the input data:
3 4 0 4 9 7 0 10 6 7 4 0 5 9 4 1
the correct result is:
4 1 6
