### 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).
