How to get intersection of two slice in golang?

by

How do I get the intersection between two arrays as a new array?

  • Simple Intersection: Compare each element in A to each in B (O(n^2))
  • Hash Intersection: Put them into a hash table (O(n))
  • Sorted Intersection: Sort A and do an optimized intersection (O(n*log(n)))

All of which are implemented here
