CF 104936F - Beavers and Revaebs

We are choosing integer values for an array of length $N$, where each position $k$ has its own allowed interval $[lk, rk]$. Once we fix a full assignment of values, we compute two families of prefix sums: one that accumulates from the left and one that accumulates from the right.
