Segment Tree Problem from SPOJ, SEGSQRSS — Sum of Squares with Segment Tree

Revision en1, by Tobby_And_Friends, 2016-10-21 22:05:32

While I do understand that the merge operation can be deduced from the equation (a + b)^2 = a^2 + b^2 — 2ab I could not specifically figure out how would I formulate the merge operation. Any help is really appreciated.
