问题
I have a list of about 1000 product ids and would like to find those that appear most frequently.
Example:
f54
f66
f54
f77
f64
f54
f66
f54
f23
And the results would be:
f54
f66
f64
f24
This will be done in either Excel 2010 (MAC) or LibreOffice.

column B are all the distinct values of column A, this is how you do it if you dont know how: http://office.microsoft.com/en-us/excel-help/filter-for-unique-values-or-remove-duplicate-values-HP010073943.aspx
C1 will be:
=COUNTIF(A1:A9,B1)
C2:
=COUNTIF(A1:A9,B2)
C3:
=COUNTIF(A1:A9,B3)
