Thank you. Clear explanation especially around point of which pointer amongst two should be incremented and reason.

Glad it was helpful!

You're welcome

Can you explain how "result.toArray(new int[result.size()][])" converts the list into a 2D Array?

[@arudhranarasimhan9150]

what does a[0] a[1] b[0] b[1] mean here ? is it predefined like 0 is begin and 1 is end in 2d array?

[@KnowledgeCenter]

Each interval has exactly 2 elements in it. 1st element i.e., at index 0 denotes start of index, 2nd element, i.e., at index 1 denotes end of interval. Yes. it's fixed.

@@KnowledgeCenter thank you so much sir.

Why copying vector!? We should take just a references auto& a = A[i];

[@KnowledgeCenter]

Yes. Can be done.
