Answers to Questions (FAQ)

How to find common items present in two lists?

dCode detects items in the lists and display common points between the two sets (i.e. the elements present in both List 1 and List 2).

Example: List 1: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 (list of even numbers)
List 2: 2, 3, 5, 7, 11, 13, 17, 19 (list of prime numbers)
Common item: 2

dCode also can detect différences between lists but also return statistical data such as precision and recall.

What is an intersection operation?

An intersection is the name given to the mathematical operation that identifies common items between two lists. It is a comparison set operator (from the set theory).

The equivalent of the intersection in the Boolean logic is the operator AND.

Example: A AND B is true only if A is true and B is true

How to represent an set intersection?

It is common to represent the common elements with a Venn diagram (with 2 rings).
