I try to understand how to write multi point crossover with numpy. For example I have two array like

```
a = np.array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
b = np.array([9, 8, 7, 6, 5, 4, 3, 2, 1, 0])
```

And K points

```
np.array([1, 5, 8])
```

Ansver shoul will be like

```
0 1 7 6 5 5 6 7 8 0
9 8 2 3 4 4 3 2 1 9
```

I figured out how it will be for two points

```
def two_point(a, b, point_1, point_2):
for i in range(point_1+1, point_2):
a[i], b[i] = b[i], a[i]
return a, b
```

But I have trouble with k points
