So far I have tried this code but couldn't approach to the optimised way of solving the problem. A small hint would be a great help instead of complete solution.

Did you solved it ?
see dolphingarlic's explanation + solution
You can use segment tree to solve this problem.
Use it for the sum and max of range l..r
When query asks a range l r you can do the following steps. 1) start with range 1, n
2) go both children (you have to go first to left one)
3) if your current range is out of required range return 0
4) if your current range is complete in required range:
{ MX = max(MX, curMX); return MX*(curR-curL+1)-curSum }5) return sum of children
I don't think this is a correct solution. (or maybe I misinterpreted it)
If I have an array [0,2,4,0] and I want to query (1,4), this solution will yield 10 as answer. (while the answer should be 4)
You can try using binary lifting + monotonic stack. :) (Just a hint)
would you like to share your solution?
tysm for the hint man, solved it because of that.
