Hello everyone,
I have several columns:
1- “Average number” columns
2- “number” columns
with number ranging from 1 to 10,000.
Normally each column belonging to group (2) should also belong to group (1) and vice versa. So we should have the same number of columns in both groups.
However, columns belonging to group 1 do not belong to group 2 and vice versa.
Example : "Average 730" but the "730" column does not exist.
The objective is to have the intersection of these 2 groups so that there are the same columns in the 2 groups.
