[Closed] Checking an array for multiple occurences?

Mar 15, 2009 10:31 pm

hello peeps,

say i have an array that contains multiple integers (not necessarily in order), is there a way of checking this array for the multiples and returning the info on how many of each occurence there are –

ie –

#(2,3,6,4,2,3,5,2,5,6,5)

returning the details –

3 instances of 2
2 of 3
1 of 4
3 of 5
2 of 6

cheers!

try this:

vetOriginal=#(2,3,6,4,2,3,5,2,5,6,5)
vetTemp=deepCopy vetOriginal

sort vetTemp

i=vetTemp.count

while i>=1 do
(
	pos=findItem vetTemp (vetTemp[i])
	format"% instances of %
"(i-pos+1) (vetTemp[i])
	i=pos-1
)

it should work.

cheers
