I came across these successful Hacking attempts... Strangely it seems as if they were submitted in order to get hacked...
If you go through their code you'll find skeptical if conditions like for problem A, for a particular value of x and y output -1 (which is an invalid answer).
Though this is an educational round but I've seen kangaroo_salesman and superman2020 getting hacked frequently in previous Div2.
Please point out if I am missing something... asking because all this felt quite absurd.
