Help with sum of distinct elements in range
By svg_af, 9 years ago, In English

Hello there

I'm trying to solve this problem with this code

I'm using a segment tree with a treap in each node and the trick from this blog

I keep getting WA on testcase 20 and i have rewritten the code a few times and debugged for hours looking for the reason

If anyone could find my error that would be really appreciated

    It's a common misconception that people think SPOJ gives WA/TLE verdict on the failed case. Actually, SPOJ runs your code on all the inputs files and then shows the verdict.
