Hi everyone, im currently solving this problem. I dont know why if i test on my computer, the answer is right but when i submit, i get WA. I suspect its because of some memory issues, but i cant find any.

Heres the test

4 1 2 2 3 1000000000

Update: My answer in the first test can be drawn in a pic like this

If we remove blue we get 2 connected components, if we remove red we get 1 connected component. So in total we get 3, which is the same with the answer. Was my understanding wrong somewhere?
