Reduction from Negative Triangle to Price Query

FROM: Negative Triangle TO: Price Query

Implications

if: to-time: $O(n^{2} / f(n))$ to answer any subsequent price query after $n$-node edge-weighted graph is preprocessed in $O(^k)$ time for some constant $k > {0}$
then: from-time: $O(n^{3} / f(n^{1/({2}k)})$
