Answers to Questions (FAQ)

How to calculate missing items in lists?

Take a List 1 and List 2, the tool is capable of returning the elements of the list 1 not present in the list 2 (missing or forgotten items), but also the elements of the list 2 not present in the read 1 (added or additional or intruders items). dCode default displays all differences between the two lists.

Example: In the list 1: C,O,D,E and list 2 : A,B,C,D,E, the only one item present in List 1 is: O, and the items presents in list 2 only are: A and B.

To list the common items and not the different ones, dCode offers a tool for common elements.

For statistical considerations of comparison of lists, see page precision and recall.

What is the XOR set operator?

The XOR (or exclusive) operation on 2 sets returns the elements that are not common to the 2 sets (the elements present in one or the other but not in both of the 2 sets).

Example: [1,2,3] XOR [2,3,4] = [1,4]
