i see you are counting letters x, for which 32 < x <= 128. as far as i remember, it should be 32 <= x < 128. perhaps this will help. regards,

i am also trying to solve this problem and i guess i have misunderstood the specification. so i have few questions:

let's denote friends' locations as a_k, 1 <= k <= n. also, let's denote arnold's house coordinates as x. then we have:

total effort in the first case is:
2*(x-a_1)^2 + 2*(x-a_2)^2 ...

hi,
i got an compiler error, because i had used the 'typeof' keyword. why is this keyword not supported? will anything like '_typeof' work? what is the g++ version used by the online judge?
