How did people solve this problem based on the fact that
max(a_1, a_2, ..., a_n) — min(a_1, a_2, ..., a_n) = x where a_1 + a_2 + ... + a_n = x^2
how is this correct?

It is not coreect for all {a_i}. The problem statement is to find such {a_i}
yes but what if a_1 = 1/a_2 that would make the relation inversely quadratic
How. a_i are positive integers. How a_1 = 1/a_2? Alse read the official solution
x = max(array) $$$-$$$ min(array) = sqrt(sum)
Then x^2 = sqrt(sum)^2 = sum
