it’s actually quite simple, i’ll explain this in boolean expression, but maybe you need different kind of approach as the limit is too big for this approach

5 1 3 1 1 1

5->1 both false

1->3 both false, but 1 has been counted

3->1 both false, but 3 has been counted

1->1 both true

1->1 both true

so in the end :
[false] [false] [false] [false] [true] [true]

but that comment can await moderation for even more than 10 days
