Unique Row Headers / Values To Subsequent Columns

I have a table similar to the table on the left, and I need to convert it to something like what is on the right. Ultimately I will concatenate the numbers in the table on the right too with commas between, so if for some reason it's easier to go straight to that, that's an option.

So in the example below, states will be listed multiple times with a unique number next to it each time. The state may be listed up to say ten times or as little as one. Each time it is listed, it will have a different number next to it. I need to reformat this into one where each state is only listed once, and each possible number is next to it in one row.
