Return Total of a Given Repeated Number in a List

[Andreas Bergendal]

Another way to do it is this:

function countOccurrences pString
   repeat for each item tItem in pString
      add 1 to tFrequencyArray[tItem]
   end repeat
   
   return tFrequencyArray
end countOccurrences

To get the number of 2’s, just extract tFrequencyArray[2] etc.
The advantage is that you get a frequency list (array) of ALL the items in one go.

The bonus advantage is that you also get a list of unique values, by getting the keys of tFrequencyArray.
So it also serves as a duplicate-clearing function, which is sometimes handy.
