p02946 AtCoder Beginner Contest 137 - One Clue
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.

Constraints

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