Usage examples

The following checks if a sorted collection contains all the values from another collection:

RETURN apoc.coll.containsAllSorted([1,4,5], [1,4]) AS output;
Table 1. Results
Output

TRUE

This function will not work on unsorted collections, as shown in the example below:

RETURN apoc.coll.containsAllSorted([1,5,4], [1,4]) AS output;
