I find maximum of the maximal influence of elixir by formula:
Math.sqrt((b1 * b1 + b2 * b2 + a1 * a1 + a2 * a2 +Math.sqrt(a1 * a1 * a1 * a1 + a2 * a2 * a2 * a2 + 8 * a1 * a2 * b1 * b2 - 2 * a2 * a2 * (b1 * b1 - b2 * b2) + 2 * a1 * a1 * (a2 * a2 + b1 * b1 - b2 * b2) + (b1 * b1 + b2 * b2) * (b1 * b1 + b2 * b2))) / 2)

...and get wa. What's wrong?

sorry, too many letters
P.S. No comments

rofl no comments :D

Don't you think, that 10^24 doesn't fit into double? =/ with your formula, you should use BigDecimal...

long long type give me WA10! When I replaced the long long to long double I get AC

You are right!
It's importent not magnitude 10^24 but
condition number of the problem and number of right
digits in result:7+9=16<18
