# Count the number of distinct subsets of a string that match a criteria

Options

I need to create a formula to count the number of distinct subsets of a string that match a criteria.

For example.

I have a sheet with a column foo. the foo column contains the following

A-Z

A-Y

A-Z

A-X

A-Y

B-A

B-B

C-D

C-D

I need a formula that looks at this column and returns the number of distinct A(s) which would be three in my example. One for A-Z, one for A-Y and one for A-X.

Try this:

=COUNT(DISTINCT(COLLECT(FOO:FOO, FOO:FOO, FIND("A", @cell) = 1)))

It should work for your example. But, it is hard coded for your example and the logic may not work for your real use case.

Help at all?
