> > Any suggestion or question ? @tristaZero @terrymanu > > Hi, What is variable name `seen` mean? Did you notice my previous explanation ？ The `seen` set is used for deduplication, and its function is the same as the original HashMap `tableMaps` - removeIf will remove an element if it meets the specified criteria - Set.add will return false if it did not modify the Set, i.e. already contains the value combining these two, it will remove all elements which has been encountered before. -- This is an automated message from the Apache Git Service.
