You are an expert competitive programmer. You will be given a problem statement, test case constraints and example test inputs and outputs. Please reason step by step about the solution (that must respect memory and time limits), then provide a complete implementation in python3.

Your solution must read input from standard input (cin), write output to standard output (cout).
Do not include any debug prints or additional output.

Put your final solution within a single code block:

# Problem
Pak Chanek has an $$$n \times m$$$ grid of portals. The portal on the $$$i$$$-th row and $$$j$$$-th column is denoted as portal $$$(i,j)$$$. The portals $$$(1,1)$$$ and $$$(n,m)$$$ are on the north-west and south-east corner of the grid respectively.

The portal $$$(i,j)$$$ has two settings:

- Type $$$t_{i,j}$$$, which is either $$$0$$$ or $$$1$$$.
- Strength $$$s_{i,j}$$$, which is an integer between $$$1$$$ and $$$10^9$$$ inclusive.

When a laser enters face $$$k$$$ of portal $$$(i, j)$$$ with speed $$$x_\text{in}$$$, it leaves the portal going out of face $$$(k+2+t_{i,j}) \bmod 4$$$ with speed $$$x_\text{out} = \max(x_\text{in},s_{i,j})$$$. The portal also has to consume $$$x_\text{out} - x_\text{in}$$$ units of energy.

Pak Chanek is very bored today. He will shoot $$$4nm$$$ lasers with an initial speed of $$$1$$$, one into each face of each portal. Each laser will travel throughout this grid of portals until it moves outside the grid or it has passed through $$$10^{100}$$$ portals.

At the end, Pak Chanek thinks that a portal is good if and only if the total energy consumed by that portal modulo $$$2$$$ is equal to its type. Given the strength settings of all portals, find a way to assign the type settings of each portal such that the number of good portals is maximised.

## Input Format
The first line contains two integers $$$n$$$ and $$$m$$$ ($$$1 \le n, m \le 1000$$$) — the number of rows and columns in the grid.

The $$$i$$$-th of the next $$$n$$$ lines contains $$$m$$$ integers, with the $$$j$$$-th integer being $$$s_{i,j}$$$ ($$$1 \leq s_{i,j} \leq 10^9$$$) — the strength of portal $$$(i, j)$$$.

## Output Format
Print $$$n$$$ lines with each line containing a string of length $$$m$$$ consisting of characters $$$0$$$ or $$$1$$$ representing the type settings. The $$$j$$$-th character in the $$$i$$$-th string is the type setting of portal $$$(i, j)$$$.

If there are multiple solutions, you can output any of them.

## Examples
```input
2 3
8 8 2
6 5 7
```
```output
110
100
```
-----
```input
1 2
420 69
```
```output
10
```

## Note
In the first example, let's consider the laser Pak Chanek shoots into face $$$1$$$ of portal $$$(2, 2)$$$. The laser travels as follows:

1. The laser enters face $$$1$$$ of portal $$$(2, 2)$$$ with speed $$$1$$$. It leaves the portal going out of face $$$3$$$ with speed $$$5$$$. Portal $$$(2, 2)$$$ consumes $$$4$$$ units of energy.
2. The laser enters face $$$1$$$ of portal $$$(2, 1)$$$ with speed $$$5$$$. It leaves the portal going out of face $$$0$$$ with speed $$$6$$$. Portal $$$(2, 1)$$$ consumes $$$1$$$ units of energy.
3. The laser enters face $$$2$$$ of portal $$$(1, 1)$$$ with speed $$$6$$$. It leaves the portal going out of face $$$1$$$ with speed $$$8$$$. Portal $$$(1, 1)$$$ consumes $$$2$$$ units of energy.
4. The laser enters face $$$3$$$ of portal $$$(1, 2)$$$ with speed $$$8$$$. It leaves the portal going out of face $$$2$$$ with speed $$$8$$$. Portal $$$(1, 2)$$$ consumes $$$0$$$ units of energy.
5. The laser enters face $$$0$$$ of portal $$$(2, 2)$$$ with speed $$$8$$$. It leaves the portal going out of face $$$2$$$ with speed $$$8$$$. Portal $$$(2, 2)$$$ consumes $$$0$$$ units of energy.

The illustration of the travel of the laser above is as follows.

As an example, consider portal $$$(2, 3)$$$. We can calculate that the total energy consumed by that portal in the end will be $$$32$$$. Since $$$32 \bmod 2 = 0$$$ and $$$t_{2,3} = 0$$$, then it is a good portal.

Now solve the problem and return the code.
