Apply TodayThe nth taxicab number, denoted as T(n), is defined as the smallest number that can be expressed as a sum of two positive algebraic cubes in n distinct ways (source: wikipedia).

Example:

T(1) = 2 = 1^3 + 1^3 T(2) = 1729 = 1^3 + 12^3 = 9^3 + 10^3

Return the value of n if the given number is a taxicab number. Return 0 if not. If the input is 1729, output would be 2, since 1729 is smallest number that can be expressed as a sum of two cubes in two (n=2) distinct ways.
