@Micah Beckman no, this solution is not an "efficient" answer even though it scores high... one should use sum(1:n) to replace a for loop sum.

Zhengyi submitted a Comment to Solution 1038560

well, I think I was wrong...This solution is slower if the degree of the polynomial is small but much faster if the degree gets higher...solving polynomials of high degree is really slow with ROOTS.

Will not solution like this be sooo much slower than simple loops?! Short yes, efficient no.
