I have some data that looks something like this…
+----------+----------+----------+
| Column 1 | Column 2 | Column 3 |
+----------+----------+----------+
| Red | Blue | Green |
| Yellow | Blue | Pink |
| Black | Grey | Blue |
+--------------------------------+
I need to go through this data and find the 3 most common colours.
The raw data is in CSV and there’s likely to be thousands more rows. (link)
What’s the best way of doing this?
There’s no magic… one row at time, one column at time.
And count each color.
