2. Complete catalan_recur function, which
recursively calculates the N-th Catalan number
from a given positive integer input n. Catalan number sequence
occurs in various counting problems. The sequence can be
recursively defined by the following equation.
And this is the high-level description of the recursive
Catalan.
