Hello everyone, can you guys help me solve this trouble please?
My story is I'm was doing this problem by using Haskell.
At first, with my submission #168264592, it got compiler error. I think because the current GHC version I use is 8.10.7, meanwhile codeforces's GHC version is 8.10.1 so it does not have module 'Data.HashMap.Strict'.
So I switch to use Data.Map.Strict which codeforces'GHC suggests, however my submission #168266690 got wrong answers. Here's the weird part: My results and the jury's result is the same, so I do not know why I got it wrong??
