Hi, I also get "Runtime Error" for the exact same testcases - other testcases solved. I'm sure it is not because of a time limit since you would get "Timeout" as a result.

To be more specific: I'm using Haskell, a self-defined segment tree (should be quite fast), and the following approach to read the next command:

solve _    0 = return ()
solve tree q = do
commandTemp <- getLine
let splittedCommand = map (\x -> read x :: Int) $ words commandTemp
...

No idea, how the Runtime Error occurs, to be honest.

EDIT: I changed my IO approach and now i get the Runtime Error in some other testcases aswell.

EDIT: It has something to do with lazy input reading - no time to dig deeper.
