Question 2
Find the largest positive integer $x$ that satisfies the equation
$$(\lfloor x\rfloor-2020)^2+(\lceil x\rceil-2030)^2=(\lfloor x\rfloor-\lceil x\rceil+10)^2.$$
(Note: If you think that the above equation has no solution in positive integers, enter your answer as “0”.)
$$(\lfloor x\rfloor-2020)^2+(\lceil x\rceil-2030)^2=(\lfloor x\rfloor-\lceil x\rceil+10)^2.$$
