Euler's totient function, also known as phi-function ϕ ( n) , counts the number of integers between 1 and n inclusive, which are coprime to n . Two numbers are coprime if their greatest common divisor equals 1 ( 1 is considered to be coprime to any number).

The optimal "splitting point" for a fixed i increases as j increases. This lets us solve for all states more efficiently. Say we compute o p t ( i, j) for some fixed i and j . Then for any j ′ < j we know that o p t ( i, j ′) ≤ o p t ( i, j) . This means when computing o p t ( i, j ′) , we don't ...
