AL AR CA NY
Doug 250 250 250 NA
Jennifer 20 340 300 100
Michele 250 500 250 60
Obama 15 45 520 600
My English is not very good, I'll try again. I want to list ALL states in
the country where Obama had greater contribution. The table above shows the
total contribution received by each candidate in a given state. To AL state
obama not received more than Doug. For the AR state he received no more than
others candidates. For the CA state he received a total of $ 520, which is
520>300>250>=250 and should be selected. In NY also had the largest
contribution, $ 600, 600>100>60 and should therefore be selected.
I want to make it to the N presidency candidates and M states of the
country. The table above is only an example.
Sorry again, for me it was clear. = (
