There are $2000001$ stones placed on a number line. The coordinates of these stones are $-1000000, -999999, -999998, \ldots, 999999, 1000000$.

Among them, some $K$ consecutive stones are painted black, and the others are painted white.

Additionally, we know that the stone at coordinate $X$ is painted black.

Print all coordinates that potentially contain a stone painted black, in ascending order.

Input is given from Standard Input in the following format:

```
$K$ $X$
```

Print all coordinates that potentially contain a stone painted black, in ascending order, with spaces in between.

-   $1 \leq K \leq 100$
-   $0 \leq X \leq 100$
-   All values in input are integers.

We know that there are three stones painted black, and the stone at coordinate $7$ is painted black. There are three possible cases:

• The three stones painted black are placed at coordinates $5$, $6$, and $7$.
• The three stones painted black are placed at coordinates $6$, $7$, and $8$.
• The three stones painted black are placed at coordinates $7$, $8$, and $9$.

Thus, five coordinates potentially contain a stone painted black: $5$, $6$, $7$, $8$, and $9$.

Negative coordinates can also contain a stone painted black.
