How do I compare the values in mutiple rows from column A, if the value of column B are identical?

My spreadsheet (MS Excel 365) has about 10 columns and 5k rows, but for the sake of simplifying it let’s consider the 2 columns I need to work with.

Column A has number values, column B has text and is sometimes blank.

Column B sometimes also repeats (only twice). These repetitions don’t always occur in consecutive rows.

What I need is, when a repetition occurs, to have a helper column that tells me which of the 2 has the greater value in column A.

I’ve tried COUNTIF but I got nowhere with it.. all that got me was different values in C, which was useless considering there are dozens of repetition instances..

EDIT: I’m adding an example as advised below. (thank you!)

C is what I would like it to show:

• 1 if there is no repetition from column B
• 1 if there is and A holds the greater value
• 2 if there is and A the lower value
