I'm want to count the occurrence of items in the first column in a csv.
The items that could occur on this list are numbers between 1 and 100.
So I am able to count the occurrence of specific values (99 in this example, see added composition), but only one at a time. But what would be the best way to iterate this 100 times ( one for each of the possible item values) in order to make a new list containing item number in column 1 and their occurrence in column 2.
composition and demo csv attatched thanks for any help!
