|You will be given B0, the first element of our sequence. The following equation must hold for all n > 0: |
0 = B0 + n+1C1B1 + n+1C2B2 + ... + n+1CnBnHere aCb is the standard binomial coefficient (see the notes). Return the value Bpos in the form "p/q" (quotes for clarity) where p and q are integers with no extra leading zeros and no common factors (other than 1). The denominator q must always be positive. If the returned value is 0 then return "0/1".
|-||aCb has value a!/(b!(a-b)!) where a! = a*(a-1)*...*2*1.|
|-||B0 will be between -100 and 100, inclusive.|
|-||pos will be between 0 and 15, inclusive.|
