# Problem A

Linear Equation Solver

## Input

There are several test cases. Each test case begins with a line containing an integer $n$, where $1 \leq n \leq 100$.

Then follow $n$ lines, each containing $n$ floating point numbers. The $j$:th number on the $i$:th row gives the entry $a_{i,j}$ of the matrix $A$. Then follows one line containing $n$ floating point numbers, the $i$:th of which is the $i$:th element of the vector $b$.

The input is ended with a case where $n = 0$.

## Output

For each operation in each test case, output the vector $x$ giving the solution to the system of equations $Ax = b$. If there are multiple vectors $x$ solving the equations, output “multiple”. If the system is inconsistent, output “inconsistent”.

The entries of $x$ are allowed to have an error of at most $10^{-3}$.
