How to get intersection of two slice in golang?

Question

Is there any efficient way to get intersection of two slices in Go?

I want to avoid nested for loop like solution

slice1 := []string{\"foo\", \"bar\",\"hello\"}

Another O(m+n) Time Complexity solution that uses a hashmap. It has two differences compared to the other solutions discussed here.

• Passing the target slice as a parameter instead of new slice returned
• Faster to use for commonly used types like string/int instead of reflection for all
