Converting range to List

Hello!, I’m pretty new to knime and I having some challenges. I have 2 columns with lower and upper limit. I now want to convert it to list instead. Can you help me on which node to use?

Sample

Input

Column A Column B

10000 10005

Output:

10001

10002

10003

10004

10005
